Modelling Human Teamwork: A Game-Theoretical and Multiagent Perspective
Alejandra López de Aberasturi Gómez - IIIA-CSIC - EN

dj. 20/Juny/2024 12:00 p.m.

This seminar explores the intersection of game theory and computer science in the study of teamwork. Traditional approaches in these fields perceive teams either as cooperative units with shared goals or as groups of self-interested agents where cooperation is necessary for individual success. However, these models fall short in capturing the nuances of human teamwork, where collaboration is not always in everyone's interest and binding agreements are often unattainable.

A novel game-theoretical model will be introduced, making collaboration in teamwork optional, allowing for the assessment of team outcomes, and letting players decide their level of engagement. Additionally, a multiagent multi-armed bandit (MA-MAB) framework will be presented, where agents empirically learn strategic behaviour approximating the Nash Equilibrium. The analysis will demonstrate how agents exhibit human-like behaviour patterns, considering the impact of team heterogeneity, task typology, and assessment difficulty on their strategies.

Alejandra López de Aberasturi is a PhD student in Artificial Intelligence at IIIA-CSIC, with research interests in Reinforcement Learning (RL) and the application of agent-based models to tackle human challenges such as resolving moral dilemmas. She holds a Master's degree in Artificial Intelligence from the Polytechnic University of Catalonia and a Master's degree in Physics and Mathematics applied to biology from the University of Granada. She also has a Bachelor's degree in Physics from the University of Granada.

Computing Shapley Values under Distributional Uncertainty
Santiago Cifuentes - University of Buenos Aires - EN

dj. 04/Abr./2024 12:00 p.m.

One of the main problems in Explaninable AI (XAI) consists in explaining, given a model M and an entity e, the prediction M(e) in such a way that the user can understand and interpret the algorithm's result. One of the most popular proposals to create such explanations consists in ranking the features of e in terms of their relevance towards the prediction from M: the better ranked features will be those more influential to the final result of the model. Many of these feature attribution techniques are conceptually based on the Theory of Cooperative Games, and this holds specially for the SHAP-score, inspired on the Shapley Values. The exact computation of the latter ones is extremally challenging, but it was proven that for certain families of simpler models (such as decision trees) they can be found in polynomial time. Nonetheless, there still exists a caveat for practical applications: their computation relies on knowledge of the underlying distribution of the feature space, which is usually unknown. Even after (boldly) assuming feature independence and sampling the distribution from the training data set, there will still be some uncertainty related to statistical deviations and noise. In this talk, I'll present different problems related to reasoning around this uncertainty, alongside (hardness) complexity results.

Santiago Cifuentes holds a Licenciate degree in Computer Science from the University of Buenos Aires, and is currently completing his PhD in Computer Science at the same institution under the advisor of Dr. Santiago Figueira and Dr. Ariel Bendersky. Over the past three years, he has been actively engaged in research projects related to Knowledge Representation and Reasoning, mainly under the presence of uncertainty and in the context of graph database models. He has already made contributions to this field with publications in JAIR, IJAR and AMW. During the last year he has started to inquire into the field of Explainable AI, and is specially interested in studying the tractability frontier for different explanability proposals. 

His PhD is related to the foundations of Quantum Computing. His main research interest in this area is quantum complexity theory, and is currently working as an Intern in the Quantum Algorithms Research Team at the Technologhy Innovation Institute of Abu Dhabi. He is also interested in understanding the relation between Quantum Physics and randomness from a computer scientist point of view (i.e. through martingale and Kolmogorov complexity notions).

Trust - The foundation for human-AI interaction
Dr. Annika Bush - Research Center Trustworthy Data Science and Security, Dortmund, Germany - EN

dt. 12/Març/2024 12:00 p.m.

Trust is a fundamental aspect of human relationships. It is based on an interplay of different concepts, such as reliance, confidence, and belief in the reliability and integrity of a person or system. Trustworthiness, therefore, encompasses qualities such as honesty, consistency, and competence, which convey a sense of security and certainty in every interaction.

In the interaction between humans and artificial intelligence, trust plays a central role in shaping the dynamics between individuals and artificial intelligence systems. In this context, it is about the reliability of AI in terms of expected performance, the transparency of its processes, and the ethical considerations that guide its decision-making processes. Just as trust is crucial in interpersonal relationships, it is equally important in fostering positive interactions between humans and AI.

In this talk, I will present the concepts of trust and trustworthiness in combination with AI and showcase some research projects on human-AI interaction with regard to diverse topics such as sustainability, education, and medicine.

Moderated Revision: Modelling what lies between Certainty and Doubt in Belief Change
Daniel Grimaldi - University of Buenos Aires - EN

dj. 07/Març/2024 12:00 p.m.

In the study of symbolic reasoning, there are various formalisms to represent and model the dynamics of knowledge, among which AGM stands out, introducing belief contraction and revision operators. These operators model the basic decision-making of an agent upon receiving a new observation. When revision is applied, the agent believes in the new observation, or equivalently, disbelieves its negation. Meanwhile, contraction makes the new observation uncertain: if originally the agent consistently believed in the observation, then neither it nor its negation is believed after the contraction. Revision can thus be seen as an operator seeking certainty (either belief or disbelief), and contraction as an operator that pursues doubt (an unsettled state).
In this presentation, we introduce a new family of operators for belief change called moderated revision. This proposal aims to incorporate a feature of balance between certainty and complete doubt. We propose this as a more adequate and general model for belief change, where revision and contraction represent extreme situations. It encompasses a diverse family tree with over 20 subfamilies, including known operators, some adaptations, and novel properties. Among them, wise and imprudent operator families emerge, reflecting responses based on the strength of the new observation: wise operators tend to doubt strong affirmations, while imprudent operators tend towards unwarranted certainty.

Daniel Grimaldi holds a Licentiate degree in Mathematical Sciences from the University of Buenos Aires and is currently completing his PhD in Computer Science at the same institution under the advisor of Prof. Dr. Vanina Martinez and Prof. Dr. Ricardo Rodriguez. Over the past four years, he has been actively engaged in research with the Logic, Language, and Computability Research Group, in addition to participating in seminars with the Buenos Aires Logic Group. This interdisciplinary experience has equipped him with a versatile skill set ideal for research in Belief Change Theory and Knowledge Representation and Reasoning. He has already made contributions to the fields, with publications in IJCAI and KR conferences, as well as in the IJAR journal. Currently, he serves as a full-time teaching assistant in the Department of Computer Science and as a researcher in training in the Institute of Computer Sciences of UBA/CONICET.

We use the previous results to characterize finitely generated projective algebras in the two varieties, which turn out to be exactly the finitely presented algebras. From the point of view of the associated logics, via Ghilardi algebraic approach to unification problems [3], this implies that their unification type is (strongly) unitary: there is always a best solution to a unification problem, and it is represented algebraically by the identity homomorphism; this is in parallel to the case of product algebras and DLMV-algebras studied in [1]. The study of unification problems is strongly connected to the study of admissible rules (or, in the algebraic setting, admissible quasiequations); a rule is said to be admissible in a logic if every substitution that makes the premises a theorem of the logic, also makes the conclusion a theorem of the logic.

As a consequence of our results, we get that the logics associated to both product hoops and DLW-hoops are structurally complete, i.e. the admissibility of rules coincides with their derivability; using results in [2], we can actually conclude that the two logics are universally complete, that is, admissibility coincides with derivability also for multiple-conclusion rules.

The main aim of this part is to deepen the understanding of the variety of product algebras P and the variety DLMV generated by perfect MV-algebras, investigating in particular the role of the falsum constant 0. As one of the main outcome of this work, we go back from hoops to the corresponding 0-bounded varieties, and we exhibit the free functor from the varieties of hoops of interest to the corresponding 0-bounded varieties. In other words, we show a construction that freely adds the falsum constant 0: starting from a product hoop (or a DLW-hoop) we obtain the product algebra (DLMV-algebra) freely generated by it.
The construction for DLW-hoops is shown to coincide with the MV-closure introduced in [1].

Lattice-ordered abelian groups, or abelian l-groups in what follows, are categorically equivalent to two classes of 0-bounded hoops that are relevant in the realm of the equivalent algebraic semantics of many-valued logics: liftings of cancellative hoops and perfect MV-algebras. The former generate the variety of product algebras, and the latter the subvariety of MV-algebras generated by perfect MV-algebras, that we shall call DLMV. In this seminar we focus on these two varieties and their relation to the structures obtained by forgetting the falsum constant 0, i.e., product hoops and DLW-hoops.

A first main result is a characterization of the free algebras over an arbitrary set of generators in the two varieties of product and DLW-hoops; the latter are obtained as particular subreducts of the corresponding free algebras in the 0-bounded varieties. More precisely, we obtain a representation in terms of weak Boolean products of which we characterize the factors. This kind of description for 0-bounded residuated lattices is present in the literature, but we are not aware of analogous results for varieties of residuated structures with just the constant 1.

We observe that in a variety that is the equivalent algebraic semantics of a logic, free (finitely generated) algebras are isomorphic to the Lindenbaum-Tarski algebras of formulas of the logic; thus their study is important from both the perspective of algebra and logic.

Quantum federated learning (part II)
Rocco Ballester Benito - Enzyme - EN

dc. 11/Oct./2023 12:00 p.m.

Federated Learning (FL) is a recent technique that emerges in order to handle the huge amount of training data needed in machine learning algorithms and the concern of privacy challenges in such models. Simultaneously, the field of Quantum Computing (QC) has grown exponentially and quantum properties such as entanglement and superposition had demonstrated to be more efficient in certain machine learning tasks, given raise to the field known as Quantum Machine Learning (QML). Thus, a handful of articles have recently studied a possible Quantum Federated Learning (QFL) framework. This paper presents an exhaustive search on this topic and aims to fill the gap in the literature in a comprehensive way. Moreover, it offers an original taxonomy of the field and proposes future challenges and remarks.

Free constructions for product hoops
Valeria Giustarini - University of Siena - EN

dc. 20/Set./2023 10:00 a.m.

Product logic is, together with Łukasiewicz logic and Gödel logic, one of the fundamental logics in Hájek’s framework of fuzzy logics arising from a continuos t-norm. In algebraic terms, this means that product algebras are one of the most relevant subvarieties of BL-algebras. From the algebraic perspective, representations of product algebras have mostly highlighted their connection with cancellative hoops; however, not much is known about the relation between product algebras and the variety of residuated lattices that constitutes their 0-free subreducts: product hoops. This contribution focuses on two main results: 1) we prove that product hoops coincide with the class of maximal filters of product algebras, seen as residuated lattices; 2) we show a construction that given any product hoop H obtains a product algebra freely generated by H; in terms of the corresponding algebraic categories, we exhibit the free functor, i.e. the left adjoint to the forgetful functor from product algebras to product hoops. 


Weak-Ensconcement: defining a new non-prioritized contraction operator
Alejandro Joaquin Mercado - Universidad de Buenos Aires, Facultad de Ciencias Exactas y Naturales - EN

dl. 18/Set./2023 12:00 p.m.

In this talk I will present the results of my undergraduate thesis on Belief Revision. I will present the weak-ensconcement: a non-prioritized order-based constructive framework for building a contraction operator. This operator characterizes an interesting family of Shielded base contractions. In turn, this characterization induces a class of AGM contractions satisfying certain postulates. Finally, I will show a connection among the class of contractions given by the weak ensconcement and other kinds of belief base contraction operators. In doing so, I will also point out a flaw I discovered in the original theorems that link the epistemic entrenchment with ensconcement (which are well established in the literature), and then I'll provide two possible solutions.

Alejandro Joaquin Mercado: "I am 23 years old and I've recently obtained my undergraduate degree in Computer Science at the University of Buenos Aires. Last year I won an scholarship to learn about Belief Revision and write my final thesis on that subject under the supervision Prof. Ricardo Rodriguez. Doing such research I've obtained intriguing results, which we then submitted as a paper at KR which was accepted for the conference's main track. Currently, I'm in the look start a PhD. My current interest is on Safe and Explainable AI. I'm curious about mixing my formal background in logic and formal proof with machine learning algorithms in order to build more explainable models".

Videogames that reason to foster spatial skills
Dr.-Ing. Zoe Falomir Llansola - Universitat Jaume I - EN

dt. 13/Juny/2023 12:00 p.m.

The challenge is to propose approaches which can solve spatial tests used to measure humans’ intelligence. On one side, we can apply these approaches in smart systems (i.e. computer games, robots) so that they can improve their spatial thinking. On the other side, we can use these approaches to help improve humans’ spatial thinking by providing them with useful feedback. I will present and discuss two cases: (1) the cube rotation test  and (2) the paper folding-and-punching test.

Zoe Falomir Llansola: Currently, I am a Ramon-y-Cajal fellow at Universitat Jaume I (UJI), Castellón, Spain. Before that, I have been a postdoc researcher for 7 years at the Spatial Cognition Center, at the University of Bremen, Germany, where I was principal investigator in projects bridging the sensory-semantic gap.I am a doctor engineer in computer science. I got my joint PhD title by UJI, Spain (Dr.) and also by University of Bremen (Dr.-Ing.). I also carried out research transfer to industry at Cognitive Robots SL where I applied results of my PhD thesis to the automation of mosaic assembling and I got the Castellón City Award for Experimental Sciences and Technology for this work. At the moment I am developing reasoning algorithms to solve spatial reasoning challenges and testing them in videogames which can be used to train people's skills. We intend to transfer these applications to education institutions in the near future. My research expertise lies in Qualitative Reasoning, Knowledge Representation techniques, Human-Machine Interaction, Machine Learning, Colour Cognition, Bioinformatics, Geographic Information Systems and Creative and Spatial Problem Solving.

Challenges and Opportunities of Asynchronous Multi-Agent Reinforcement Learning
Enrico Marchesini - Northeastern University - EN

dt. 23/Maig/2023 12:00 p.m.

Real setups pose significant challenges for modern Deep Reinforcement Learning algorithms; agents struggle to explore high-dimensional environments and have to provably guarantee safe behaviors under partial information to operate in our society. In addition, multiple agents (or humans) must learn to interact while acting asynchronously through temporally extended actions. I will present our work on fostering diversified exploration and safety in real domains of interest. We tackle these problems from different angles, such as (i) using Evolutionary Algorithms as a natural way to foster diversity; (ii) leveraging Formal Verification to characterize policies' decision-making and designing novel safety metrics to optimize; (iii) designing macro-action-based algorithms to learn coordination among asynchronous agents.

Enrico Marchesini is a Postdoctoral research associate in the Khoury College of Computer Sciences at Northeastern University, advised by Christopher Amato. He completed his Ph.D. in Computer Science at the University of Verona (Italy), advised by Alessandro Farinelli. His research interests lie in topics that can foster real-world applications of Deep Reinforcement Learning. For this reason, he is designing novel algorithms for multi-agent systems while promoting efficient exploration and safety in asynchronous setups.

I will then focus on a recent paper co-authored by Ricard Sole and Clement Moulin-Frier (, in which we model adaptive dynamics in complex ecosystems. Building on the Forest-Fire model, the study uses fire as an external, fluctuating force in a simulated environment. Agents must balance tree harvesting and fire avoidance, resulting in the evolution of an ecological engineering strategy that optimally maintains biomass while suppressing large fires. We will discuss the implications of these findings for AI management of complex ecosystems, emphasizing the potential benefits of incorporating MARL and collaboration strategies into environmental management and conservation efforts.

dj. 30/Març/2023 12:00 p.m.

In this talk decision-making and temporal tasks inspired by Boolean functions are analyzed, exploring connectivity patterns, dynamics, and biological constraints of recurrent neural networks (RNNs) after training. The focus of such models in Computational Neuroscience is brain regions such as the cortex and prefrontal cortex and their recurrent connections related with different cognitive tasks. Understanding the dynamics behind these models is crucial for building hypotheses about brain function and explaining experimental results.

Dynamics is analyzed through numerical simulations, and the results are classified and interpreted. The study sheds light on the multiplicity of solutions for the same tasks and the link between the spectra of linearized trained networks and the dynamics of their counterparts. The distribution of eigenvalues of the recurrent weight matrix was studied and related to the dynamics in each task. Approaches and methods based on trained networks are presented. The importance of having a software framework that facilitates testing different hypotheses and constraints is also emphasized.

Cecilia Jarne did her PhD in physics at the IFLP and the Physics Department of the National University of La Plata and a PostDoc at the Buenos Aires University Physics department (IFIBA). Her research experience is based on large data sets analysis, programming and modelling, first in high-energy cosmic ray physics and then during her postdoctoral research analyzing bird songs and dynamics.  Currently, she is an assistant researcher and Professor at Universidad Nacional de Quilmes and  CONICET working on Recurrent Neural Networks and Complex Systems since 2018.

An epistemic approach to model uncertainty in data-graphs
Nina Pardal - Department of Computer Science, University of Sheffield, UK - EN

dt. 28/Març/2023 12:00 p.m.

Graph databases are becoming widely successful as data models that allow to effectively represent and process complex relationships among various types of data. Data-graphs are particular types of graph databases whose representation allows both data values in the paths and in the nodes to be treated as first class citizens by the query language. As with any other type of data repository, data-graphs may suffer from errors and discrepancies with respect to the real-world data they intend to represent. In this talk, we explore the notion of probabilistic unclean data-graphs in order to capture the idea that the observed (unclean) data-graph is actually the noisy version of a clean one that correctly models the world, but that we know of partially. As the factors that yield to such observation heavily depend on the application domain and may be the result of different types of clerical errors or unintended transformations of the data, we consider an epistemic probabilistic model that describes the distribution over all possible ways in which the clean (uncertain) data-graph could have been polluted. Based on this model, we study data cleaning and probabilistic query answering for this framework and present complexity results when the transformation of the data-graph is caused by either removing (subset), adding (superset), or modifying (update) nodes and edges.

Dr. Nina Pardal is currently a Research Associate at the Department of Computer Science of the University of Sheffield, in the UK. She obtained a PhD in Mathematics from the University of Buenos Aires, Argentina, and a PhD in Computer Science from the University Paris-Nord, France.

Paradigm Shift in the Engineering Design Cycle
Dr. Cihan Ates - Karlsruhe Institute of Technology (KIT), Germany - EN

dt. 29/Nov./2022 11:00 a.m.

Engineers have been dealing with massive amounts of data accumulated over decades of fundamental experiments and field measurements, vitalized in the form of cleverly organized charts, tables and heuristic laws. In the last few decades, our capability to generate data has increased even further with the developments in (i) the digital measurement techniques including sensing technologies, (ii) computational power, (iii) faster, easier and cheaper data transfer and storage and (iv) post-processing tools and algorithms. On the other side, the problems that are needed to be addressed today, such as the food-water-energy security, pandemics and diseases, or global warming, are massive and at a completely different scale. More drastically, we have comparably much less time to find sustainable solutions. Therefore, we need a paradigm shift in how to interpret the data we collect and solve our problems, which can speed up our hypothesis test cycle. In this talk, we will visit some case studies relevant to the energy problem and discuss how the expertise of AI specialists can tip the scales in our favour.  

Cihan is a junior research group leader at KIT, under the Institute of Thermal Turbo Machinery, Multiphase Flow & Combustion group. With his group, he is working on the design and optimization of energy intensive processes.

Smart Traffic Control for the Era of Autonomous Driving
Associate Professor Dongmo Zhang - Western Sydney University, Australia - EN

dj. 24/Nov./2022 12:00 p.m.

Over the last decade, the research on autonomous vehicles (AVs) has made revolutionary progress, which brings us hope of safer, more convenient, and more efficient means of transportation. Most significantly, the advance of artificial intelligence (AI), especially machine learning, allows a self-driving car to learn and adapt to complex road situations with millions of accumulated driving hours, which are way higher than any experienced human driver can reach. However, autonomous vehicles on roads also introduce new challenges to traffic management, especially when we allow them to travel mixed with human driving vehicles.

New theories for better understanding of the new era of transportation and new technologies for smart roadside infrastructures and intelligent traffic control are crucial for development and deployment of autonomous vehicles. This presentation will discuss some of these challenges, especially the social aspects of autonomous driving, including interaction between autonomous vehicles and roadside infrastructures, mechanisms of traffic management, the price of anarchy in road networks and automated negotiation between vehicles.

Dongmo Zhang is an Associate Professor in Computer Science and Associate Dean Graduate Studies in School of Computer, Data and Mathematical Sciences at Western Sydney University. He is a leading researcher in Artificial Intelligence, working in a wide range of areas, including multi-agent systems, strategic reasoning, automated negotiation, belief revision, reasoning about action, auctions, trading agent design etc. He has published around 150 papers in international journals and conferences, including the top AI Journals, such as AIJ, AAMAS & JAIR, and the top AI conferences, such as IJCAI, AAAI & AAMAS.  He has been an area chair, senior PC or PC for many top AI conferences, IJCAI, AAAI, ECAI, PRICAI, AJCAI, AAMAS, KR&R etc. He and his research team have also received several international awards, such champions of Trading Agent Competitions and best paper awards.

From implicative reducts to Mundici’s functor
Valeria Giustarini - University of Siena - EN

dt. 22/Nov./2022 02:00 p.m.

The connection between substructural logics and residuated lattices is one of the most relevant results of algebraic logic. Indeed, it establishes a framework where different systems, or equivalently, classes of structures, can be both compared and studied uniformly. Among the most well-known connections among different structures in this framework surely stands Mundici’s theorem, which establishes a categorical equivalence between the algebraic category of MV-algebras and lattice-ordered abelian groups (abelian l-groups in what follows) with strong order unit (an archimedean element with respect to the lattice order), with unit preserving homomorphisms. This equivalence, connecting the equivalent algebraic semantics of infinite-valued Lukasiewicz logic (i.e., MV-algebras) with ordered groups, has been deeply investigated and also extended to more general structures.

Alternative algebraic approaches to Mundici’s functor have been proposed by other authors. In the present contribution we re-elaborate Rump’s work, which is inspired by Bosbach’s idea, and focuses on structures with only one implication and a constant (whereas Bosbach’s cone algebras have two implications). The key idea is to characterize which structures in this reduced signature embed in an l-group. We find conditions that are different (albeit equivalent) to the ones found by Rump, and moreover we extend some of Rump’s constructions to categorical equivalences of the algebraic categories involved.

Valeria Giustarini is a Master Student at the Department of Information Engineering and Mathematics, University of Siena.

Value alignment in human-AI societies
Enrico Liscio - TU Delft - EN

dt. 22/Nov./2022 12:00 p.m.

As artificial agents become increasingly embedded in our society, we must ensure that they align with our human values, both at a level of individual interactions and system governance. However, agents must first be able to infer our values, i.e., understand how we prioritize values in different situations, both as individuals and as society. In this talk we explore how artificial agents can infer our values, while helping us reason about them. How can artificial agents understand our deepest motivations, when we are often not even aware of them?

Enrico Liscio is a PhD candidate in the Interactive Intelligence Group at TU Delft and part of the Hybrid Intelligence Centre. His research focuses on Natural Language Processing techniques to estimate human values from text. His work is part of the project to achieve high-quality online mass deliberation, creating AI-supported tools and environments aimed at transforming online conversations into more constructive and inclusive dialogues.

How to Save Democracy (or Towards Model Checking of E-Voting Protocols in Alternating-time Temporal Logic)
Wojtek Jamroga - University of Luxembourg and Polish Academy of Sciences - EN

dt. 15/Nov./2022 12:00 p.m.

Properties of coercion resistance and voter verifiability refer to the existence of an appropriate strategy for the voter, the coercer, or both. One can try to specify such properties by formulae of a suitable strategic logic. However, automated verification of strategic properties is notoriously hard, and novel techniques are needed to overcome the complexity.

I will start with an overview of the relevant properties, show how they can be specified, and present some new results for model checking of strategic properties.

Wojtek Jamroga is an associate professor at the Polish Academy of Sciences and a research scientist at the University of Luxembourg. His research focuses on modeling, specification and verification of interaction between agents. He has coauthored over 100 refereed publications, and has been a Program Committee member of most important conferences and workshops in AI and multi-agent systems. His research track includes the Best Paper Award at the main conference on electronic voting (E-VOTE-ID) in 2016, and a Best Paper Nomination at the main multi-agent systems conference (AAMAS) in 2018.

Computational Game Theory course - Prof. Mike Wooldridge

dl. 27/Juny/2022 10:00 a.m. - dv. 01/Jul./2022 01:00 p.m.

Game theory is the mathematical theory of strategic interactions between self-interested agents. Game theory provides a range of models for representing strategic interactions, and associated with these, a family of solution concepts, which attempt to characterise the rational outcomes of games.

Game theory is important to computer science for several reasons: First, interaction is a fundamental topic in computer science, and if it is assumed that system components are self-interested, then the models and solution concepts of game theory seems to provide an appropriate framework with which to model such systems. Second, the problem of computing with the solution concepts proposed by game theory raises important challenges for computer science, which test the boundaries of current algorithmic techniques.

This course aims to introduce the key concepts of game theory for a computer science audience, emphasising both the applicability of game theoretic concepts in a computational setting, and the role of computation in game theoretic problems.


Building Contrastive Explanations for Multi-Agent Team Formation
Athina Georgara - IIIA-CSIC - EN

dt. 14/Juny/2022 12:00 p.m.

It is undenyable that more and more hard and complex procedures are being automated with the aid of artificial intelligence, having led to an era where artificial intelligence can be practically found in any system. As such, it is more and more common that people make decisions guided by the suggestions and recommendations of some intelligent system. As these systems support everyday life’s decisions they unavoidably make people curious about their functionality.Thus, the need for humans to understand the rationale behind AI decisions becomes imperative. 

Adequate explanations for decisions made by an intelligent system do not just help describing how the system works, they also earn users’ trust. In this work we focus on a general methodology for justifying why certain teams are formed and others are not by a team formation algorithm (TFA). Specifically, we introduce an algorithm that wraps up any existing TFA and builds justifications regarding the teams formed by such TFA. This is done without modifying the TFA in any way. Our algorithm offers users a collection of commonly-asked questions within a team formation scenario and builds justifications as contrastive explanations. We also report on an empirical evaluation to determine the quality of the explanations provided by our algorithm.

Athina Georgara is currently a PhD candidate in Autonoma Unoversity of Barcelona in collaboration with the Artificial Intelligence Research Institute under the supervision of professors Carles Sierra and Juan A. Rodríguez-Aguilar. Her PhD studies are funded by the consulting company Enzyme Advising Group, where she is employeed during her studies. Athina completed her undergraduate studies and acquired a diploma degree at the school of Electrical and Computer Engineering in Technical University of Crete, and she acquired an M. Sc. in Electronic and Computer Engineering in the same school under the supervision of associate professor Georgios Chalkiadakis.

The scope of her research lies on team formation and task allocation. She works towards automating the process of forming efficient teams for assigning them to tasks combining findings from organisational psychology and social sciences. Due to her prior engagement on the fields Athina also holds interest on Algorithmic Game Theory and Machine Learning, along with their implementation in Multi-agent Systems.

Towards Pluralistic Value Alignment: Aggregating Value Systems through ℓp-Regression
Roger Xavier Lera Leri - IIIA-CSIC - EN

dt. 07/Juny/2022 12:00 p.m.

Dealing with the challenges of an interconnected globalised world requires to handle plurality. This is no exception when considering value-aligned intelligent systems, since the values to align with should capture this plurality. So far, most literature on value-alignment has just considered a single value system. Thus, in this talk I will discuss a method for the aggregation of value systems. By exploiting recent results in the social choice literature, we formalise our aggregation problem as an optimisation problem, more concretely, as an ℓp-regression problem. Moreover, our aggregation method allows us to consider a range of ethical principles, from utilitarian (maximum utility) to egalitarian (maximum fairness).

Roger Lera finished the BSc in Physics in the University of Barcelona in 2020. He is currently a Ph.D. student at the Artificial Intelligence Research Institute (IIIA-CSIC) in Bellaterra, Spain. His research interest are ethics & AI, Explainable AI and combinatorial optimisation problems for real-world applications.

Towards a logico-algebraic setting for counterfactual conditionals
Giuliano Rosella - Universidad de Turin - EN

dc. 01/Juny/2022 10:00 a.m.

In the present seminar, we present a class of algebras obtained by adding a normal modality to Boolean algebras for conditionals so as to provide an algebraic setting for the logic C1 for counterfactual conditionals, axiomatized by Lewis. These modal algebras, that we name “Lewis algebras”, are particular Boolean algebras with operators and, as such, allow a dual relational counterpart that will be called Lewis frames. The main results of this paper show that: (1) Lewis algebras and Lewis frames provide a sound semantics for Lewis logic C1; (2) Lewis’ original sphere semantics for counterfactuals can actually be defined from Lewis frames, and hence, from Lewis algebras. Finally, we will present a new logic for counterfactuals that, taking inspiration from the definition of Lewis algebras, is obtained as a modal expansion of the recently introduced logic LBC to reason about Boolean conditionals.

Some shallow remarks on the use of values in artificial autonomous systems
Pablo Noriega - IIIA-CSIC - EN

dt. 31/Maig/2022 12:00 p.m.

I propose to peek into the possibility of using moral values as a device to harness the autonomy of artificial systems. The talk should outline the challenge of developing a theory of values that has a distinctive AI bias: its motivation, the foundational questions, the distinctive features, the potential artefacts, the methodological challenges, and the practical consequences of such a theory. Fortunately for everyone, it will not. The talk will only look into a restricted understanding of the problem of embedding values into the governance of autonomous systems. In fact, I will only pay attention to some of the obvious practical problems one needs to overcome if one intends to claim that an autonomous system is aligned with a particular set of values. Hopefully, this timid approach will reveal enough of the breath and beauty of an artificial axiology to justify taking a closer look into it.


Pablo Noriega is a tenured scientist of the IIIA. His main research interest is in the governance of open multiagent systems. This talk reflects recent collaboration with Mark d'Inverno (Goldsmiths, U.of London), Julian Padget (U. of Bath), Enric Plaza (IIIA), Harko Verhagen (Stockholm U.) and Toni Perello-Moragues.

A Framework for XAI in Socio-Technical Systems
Maria Vanina Martinez - University of Buenos Aires, Argentina - EN

dt. 17/Maig/2022 12:00 p.m.

With the availability of large datasets and ever-increasing computing power, there has been a growing use of data-driven Artificial Intelligence systems, which have shown their potential for successful application in diverse domains related to social platforms. However, many of these systems are not able to provide information about the rationale behind their decisions to their users. Lack of understanding of such decisions can be a major drawback, especially in critical domains such as those related to cybersecurity, of which malicious behavior in social platforms is a clear example. This phenomenon has many faces, which for instance appear in the form of bots, sock puppets, creation and dissemination of fake news, Sybil attacks, and actors hiding behind multiple identities. In this talk, we discuss  HEIST (Hybrid Explainable and Interpretable Socio-Technical systems), a framework for the implementation of intelligent socio-technical systems that are explainable by design, and study an instantiation for analysis of fake news dissemination.


Dr. Maria Vanina Martinez obtained her PhD at University of Maryland College Park and pursued her postdoctoral studies  at Oxford University in the Information Systems Group in Artificial Intelligence (AI) and Database Theory. Currently, she is an adjunct researcher at CONICET as a member of the Institute for Research in Computer Science (ICC, UBA - CONICET) and an assistant professor at the Department of Computer Science at University of Buenos Aires, Argentina.

Morphological classification of galaxies with deep learning
Helena Domínguez Sánchez - Institute of Space Sciences (ICE-CSIC) - EN

dt. 10/Maig/2022 12:00 p.m.

Galaxies exhibit a wide variety of morphologies which are strongly related to their star formation histories. Having large samples of morphologically classified galaxies is fundamental to understand their formation and evolution. In this talk, I will review my research related to deep learning algorithms for morphological classification of galaxies which have resulted in the release of morphological catalogues for large international surveys such as SDSS, MaNGA or Dark Energy Survey. I will describe the methodology, based on  supervised learning and convolutional neural networks (CNN). The main disadvantage of such approach is the need of large labelled training samples which we overcome by applying transfer learning or by ‘emulating’ the faint galaxy population. 

Helena Domínguez Sánchez is a research fellow astrophysicist at Institute of Space Sciences (ICE-CSIC) trying to understand how and why the properties of galaxies have changed across the history of the Universe. During the last years, she has pioneered the use of Deep Learning techniques in astronomy.

All chips great and small
Luis Fonseca - Institute of Microelectronics of Barcelona (IMB-CNM, CSIC) - EN

dt. 03/Maig/2022 12:00 p.m.

75 years ago the transistor was invented. In hindsight, that moment can be considered the big bang of the Information Society we are living in today. The recent semiconductor crisis has shown how important chips are in our world. However, it is relatively unknown what chip-making entails. Moreover, chips come in many forms. Leveraging on IMB-CNM activities, I would like to show that miniaturization and scalability makes possible not only place chips inside computers and smartphones, but also to deploy microdevices in so demanding and so far apart scenarios as inside living cells and on-board of space missions.

Luis Fonseca has developed his scientific career at the Institute of Microelectronics of Barcelona. Physicist by training he joined IMB-CNM in 1989 as a predoc and he is today its current director. His scientific interests have revolved about micro and nanotechnologies for gas sensing and energy harvesting.

The Influence of Social Motivation on Decision-Making between Precision Movements: A Computational Approach
Ignasi Cos - Universitat de Barcelona - EN

dt. 26/Abr./2022 12:00 p.m.

Reward is a foundation of behaviour: we move to attain valuable states. However, moving towards those states implies investing some effort and deploying motor strategies that are very much dependent on the person’s motivation. We performed a decision-making task in with human participants had to accumulate reward by selecting one of two reaching movements of opposite motor cost, to be performed precisely. Our results show that performance and social status were taken into consideration by diminishing error as a function of the partner. This also transpired into an increase movement time between the baseline condition and any social condition. We interpret this as an adaptive process of trade-off between precision, reward and time. Other effects on the movement amplitude became significant when the skill of the companion player was clearly unattainable, such as a reduction of the amplitude, thus escaping the traditional context of the speed-accuracy trade-off. As a context for the study of motivation and motor adaptation we developed a model based on movement benefit and costs optimization. Remarkably, its predictions show that this optimization depends on the context where the movements and the choices are performed, incorporating motivation as part of its internal dynamics.

Ignasi Cos (Barcelona, 1973; MEng Electronics 1996 – Politecnico di Torino, MEng Telecomunications 1997 – Universitat Politècnica de Catalunya; PhD in Cognitive Science and Artificial Intelligence 2006 - University of Edinburgh).

Computerització i ètica: un debat sobre els reptes actuals
Norbert Bilbeny Garcia - Universitat de Barcelona - CA

dt. 22/Març/2022 12:00 p.m.

L´ètica ha consistit, fins ara, en una relació dels éssers humans entre ells i guiada per ells mateixos, en condicions bàsiques de presencialitat, reciprocitat, discursivitat i intersubjectivitat, tot suposant en cada individu la capacitat de guiar la seva acció, més enllà de l´instint i dels interessos primaris, per l´aprenentatge social de pautes de conducta moral i l´aplicació d´aquestes a partir d´un procés individual de decisió basat en l´ús personal de les facultats de sentir, raonar, voler i reflexionar, comunes amb la resta d´individus.

La computerització transforma totes les esmentades facultats i condicions de decisió de la conducta moral. Hem de veure en quina mesura, i quins poden ser els principals inconvenients i avantatges en relació a allò que encara pensem com a “ètica”. O és que la noció d´aquesta també està en revisió? Ciència i filosofia tenen ara el repte de respondre i apuntar vers alguna direcció favorable als interessos de la humanitat.

Norbert Bilbeny i García és professor universitari, filòsof i escriptor, catedràtic d'ètica a la Universitat de Barcelona. Fou degà de la Facultat de Filosofia, essent escollit el 2011, des d'on va defensar un model d'internacionalització de la investigació catalana i la transferència societat-universitat. Actualment és director del Màster de Ciutadania i Drets Humans, i ho va ser del Màster d'Immigració i Educació intercultural.

Challenges and opportunities of artificial intelligence for empowering people living with chronic conditions
Luís Fernández-Luque - Adhera Health Inc. - EN

dt. 15/Març/2022 12:00 p.m.

The health domain has been an application area of artificial intelligence since the early years. Until very recently the use of artificial intelligence in the health domain has mostly focused on clinical data, including images, genetics, and clinical records. It has not been until recently that data-driven solutions in the health domain started to rely on patient-generated data coming from social networks, mobile and wearable devices.  These include applications for classification, health outcome predictions, conversational agents, and recommender systems. This lecture will focus on the human factors and applications of artificial intelligence for empowering people living with chronic conditions. We will discuss the main technical challenges and their human factors implications for the building of actionable and trustworthy solutions that support patients, caregivers, and their clinicians.

Luís Fernández-Luque: My research focus has been on the adaptation of mobile and web technologies for patient support and public health. My scientific contributions in mobile health, which includes both mobile and wearable devices, are among the most cited and pioneering in the field dating back to the year 2006. I have substantial contributions in the creation and validation of Artificial Intelligence applications based on mobile and wearable technologies, including technologies such as deep learning and health recommender systems. My career has been always focused on the crossroads between computer science and behavioral change. I have ample experience in combining human factors research with artificial intelligence, that know-how is of crucial importance for the successful completion of the two aims of the project. My focus on human factors and data-driven applications dates back to my Ph.D. dissertation which focused on trustworthiness aspects of information retrieval of patient education.

As Chief Scientific Officer at Adhera Health (Palo Alto, CA, USA), I oversee the implementation of our research roadmap for our digital therapeutics' platform. Our evidence-based platform combines mobile technologies with artificial intelligence (Recommender Systems) to provide personalized patient support designed to improve the physical and mental wellbeing of people living with chronic conditions. In addition, I am a senior member of the IEEE Engineering in Medicine and Biology Society and Vice-President of the International Medical Informatics Association. I have over 100 publications cited in Google Scholar (  

Blockchains, DAOs, and fractal governance: a preliminary overview
Marta Poblet Balcell - RMIT University - Graduate School of Business and Law - EN

dt. 08/Març/2022 12:00 p.m.

In the last few years, blockchain technologies have fuelled the emergence of DAOs (Decentralised Autonomous Organisations) as socio-technical systems pursuing a variety of goals: decentralise finances, raise funds, create guilds, promote cultural and artistic initiatives, etc. Developments in this space have also gone hand in with innovations in governance technologies (on-chain and off-chain voting systems, legal smart contracts, coordination tools, etc.). This presentation will provide a preliminary overview of how DAOs have are deploying governance mechanisms aiming at progressive decentralization and autonomy, while also considering the limitations and challenges that these systems are grappling with as they claim their space in the Web 3.

Evolution as a principle for engineering photosynthesis
Ivan Reyna-Llorens - Centre for Research in Agricultural Genomics (CRAG) - EN

dt. 01/Març/2022 12:00 p.m.

As the world population continues to expand, it is predicted that crop yields will have to increase by 50% over the next 35 years. Traditional breeding programs cannot keep pace with this current population growth rate. One of the main determinants of crop yield is the capacity of the plant to harvest light and convert it into sugars through photosynthesis. Despite this, photosynthesis improvement is still underexploited for the purpose of increasing yield. Plants have evolved a wide variety of photosynthesis flavours, some of them more efficient than others. This provides an “evolutionary guide” for engineering some of these traits in target crops like rice. In this talk I will describe some of the strategies we use in improving photosynthesis and some of the problems we face where the interaction with researchers in Artificial intelligence could prove beneficial.

Ivan Reyna-Llorens received a Ph.D in Plant Sciences from the University of Cambridge in 2016 using evolution as a guide to improve agricultural traits. He then worked as a postdoctoral fellow in the same University looking to develop methods for studying plant genomes. In 2021 he started the synthetic biology and photosynthesis group as a Junior Group Leader at CRAG focusing on understanding how global re-arrangements of gene regulatory networks have shaped the evolution of photosynthesis in plants, more specifically the adaptation of the photosynthetic machinery to different light conditions.  

From Transfer Learning to Continual Learning
Joost van de Weijer - Computer vision center - EN

dt. 22/Feb./2022 12:00 p.m.

One of the major assets of deep neural networks is that when trained on large data sets (source data), their knowledge can be transferred to small datasets (target data). Transfer learning for deep neural networks can be simply performed by finetuning the network on the new data. In this talk, I will introduce the research field of continual learning where the aim is to not only adapt to the target data but also keep the performance on the original source data. In addition, during adaptation to the target, the learner has no longer access to the source data.  This process can be repeated into a sequence of tasks that are learned one at a time. The aim for the learner is to perform well on all previous tasks at the end of the training process. The main challenge for continual learning is called catastrophic forgetting, where the learner suffers from a significant drop in performance on previous tasks. I will discuss a number of strategies to prevent catastrophic forgetting and will explain several methods developed in our group to address this problem. 

Joost van de Weijer is a Senior Scientist at the Computer Vision Center and leader of the Learning and Machine Perception (LAMP) group. He received his Ph.D. degree in 2005 from the University of Amsterdam. From 2005 to 2007, he was a Marie Curie Intra-European Fellow in the LEAR Team, INRIA Rhone-Alpes, France.

The Mathematical Characterization of Brain States
Ignasi Cos - Universitat de Barcelona - EN

dt. 25/Gen./2022 12:00 p.m.

How useful would it be to attain a formal, mathematical characterization of the neuro-dynamics of individual patients affected by stroke, Parkinson’s Disease or other neuro-degenerative disorders in a straightforward manner? Beyond the obvious clinical application, the answer to that question depends on attaining accurate models of the brain, on how general are their predictions, and on how adaptive to the clinical context and in particular to the single patient medical praxis. Current tools for brain state characterization have made a remarkable progress in the past ten years, yielding mathematical techniques, gradually amassing a huge amount of knowledge about brain structure and dynamics during resting state and performance of specific tasks. Pending further research to perfect them, these techniques are to emerge as promise both for a deeper, more formal understanding of brain function, and as a reliable tool for the clinical diagnose of neuro-degenerative disorders.

Estimating Context-Specific Values from Natural Language
Enrico Liscio - TU Delft - EN

dt. 23/Nov./2021 12:00 p.m.

Values are the abstract motivations that justify opinions and actions. The pursuit of values drives human behavior and promotes cooperation. Existing research is focused on general (e.g., Schwartz) values that transcend contexts. However, the context-specific nature of values must be considered to (1) understand human decisions, and (2) engineer intelligent agents that can elicit human values and take value-aligned actions. Further, in practical applications (e.g., to conduct meaningful conversations or to identify online trends), artificial agents should be able to understand values on the fly from natural language.

We outline an approach for estimating context-specific values from text. At first, the values relevant to a context must be identified. To this end, we propose Axies, a hybrid (human and AI) methodology to identify context-specific values. Then, we examine the effectiveness of NLP models in classifying values in text. As context influences how we express values in natural language, we investigate the extent to which the learned value rhetoric can be transferred across contexts. Subsequently, we propose explainability techniques to inspect whether value classifiers have learned the context-specific connotations of values. Finally, we combine the steps above into a single method for swiftly estimating context-specific values from users.

Enrico Liscio ( is a PhD candidate in the Interactive Intelligence Group at TU Delft and part of the Hybrid Intelligence Centre. He obtained cum laude MSc. in Systems and Control from TU Delft (the Netherlands, 2017) and cum laude BSc. in Automation Engineering from the University of Bologna (Italy, 2015). Between his MSc. studies and the current position, he worked for 2.5 years as deep learning developer and technical project lead at Fizyr (the Netherlands).

Agent and Multi-agent Techniques for Resource Allocation and Scheduling in Earth Observation Satellite Constellations
Gauthier Picard - ONERA/DTIS, Université de Toulouse - EN

dt. 16/Nov./2021 12:00 p.m.

In this presentation, we discuss the use of Agent and Multi-agent techniques in Space systems. We first identify some AI research challenges related to satellite constellations, especially concerning Earth Observation applications. These challenges range from constellation design to on-board in-space decision, and raise opportunities for investigation efforts in Multi-agent based Simulation, to Distributed Problem Solving, by the way of Machine Learning and Game Theory. We then focus on case studies related to constellation resource allocation and scheduling. The first case study concerns the allocation of exclusive orbit slots to privileged constellation users. In this problem, the constellation operator aims at allocating the resources (orbit slots) as optimally and fairly as possible, prior to any scheduling, only using some simple requirements from clients. This problem is long-term, over horizons of several months. We explore here the use of utilitarian and Leximin-optimal techniques. The second case study investigates how distributed and coordinated decision techniques can be used as to schedule observation tasks over such exclusive orbit portions, so that exclusive users do not disclose their own agenda. This problem is short-term, over horizons of few hours. Here, we make use of distributed constraint optimization and sequential auctions to distribute decisions over the set of exclusive users.

Gauthier Picard received a Ph.D. in Computer Science from the University of Toulouse in 2004, and the Habilitation degree in Computer Science from the University of Saint-Etienne in 2014. He was Associate Professor and then Full professor in Computer Science at MINES Saint-Etienne, before reaching a Senior Researcher position at ONERA, The French Aerospace Lab. His research focuses on cooperation and adaptation in multi-agent systems and distributed optimization with applications to aircraft design, ambient intelligence, intelligent transport and space operations.

Social media analysis and crowd-sourcing for disaster management
José Luis Fernández Marquez - University of Geneva - EN

dt. 09/Nov./2021 12:00 p.m.

Increase in access to mobile phone devices and social media networks has changed the way people report and respond to disasters. Community-driven initiatives such as Stand By Task Force (SBTF) or GISCorps have shown great potential by crowdsourcing the acquisition, analysis, and geolocation of social media data for disaster responders. To make social media information suitable for emergency responders, these initiatives face two main challenges: (1) Most of social media content such as photos and videos are not geolocated, thus preventing the information to be used by emergency responders,  and (2) they lack tools to manage volunteers' contributions and aggregate them in order to ensure high quality and reliable results.
 This seminar illustrates Crowd4EMS a crowdsourcing platform developed under the EU project E2mC: Evolution of Emergency Copernicus services. Crowd4EMS combines automatic methods for gathering information from social media and crowdsourcing techniques in order to manage, aggregate volunteers' contributions, and ensure reliable for emergency responders in disaster management.

Dr. Jose Luis Fernandez-Marquez (Male) is Senior Lecturer at the University of Geneva (UNIGE), and  head of the Geneva-Tsinghua Initiative Accelerator.  He has a computer science background, PhD in collective artificial intelligence, and wide experience in Citizen Science.  In 2011 he joint UNIGE after his PhD defence at the Artificial Intelligence Research Institute (IIIA-CSIC).  In 2014, he formally joint the Citizen Cyberlab a partnership between UNIGE, CERN, and the United Nation for Training and Research (UNITAR) aiming at encouraging citizens and scientists  to collaborate in new ways to solve big challenges. Since 2019, he is technical coordinator of the Crowd4SDG EU project which focuses on demonstrating the potential of Citizen Science for monitoring and achieving the SDGs.

His current research focus on citizen science data quality analysis and methodologies to make citizen science data  suitable for decision/policy makers. 

Simulating the Future of Mobility: How can AI help?
Dídac Busquets - Chief Scientist at Immense Simulations - EN

dt. 02/Nov./2021 12:00 p.m.

In recent years, mobility has undergone a massive change. Car sharing, car pooling, shared e-scooters or bikes are a few examples of new mobility services that have appeared lately. The typical paradigm of owning a car is also changing, especially with the soon-to-come autonomous vehicles. On top of that, the pandemic the world is living has also changed mobility patterns and behaviours. With such an unpredictable situation, all stakeholders (from local authorities, to mobility service providers, or vehicle manufacturers) need tools to evaluate future scenarios and understand how best to respond to mobility demand. This has often been done with very specific and complicated tools, only available to specialised consultants. At Immense we have developed an easy to use simulation platform that allows non experts users to quickly formulate "what if" questions regarding mobility scenarios. In this talk I'll give an overview of our platform, making special emphasis on how AI can help in this area.

Didac Busquets is a Computer Scientist specializing in Artificial Intelligence, and more specifically on agent-based simulation, task and resource allocation, self-organization, and robotics. He has a BSc (1999) and PhD (2003) in Computer Science, both from the Technical University of Catalonia (UPC).  After completing his PhD in the area of Robotics at IIIA, he obtained a Fulbright Research Fellowship to do a postdoc at Carnegie Mellon University. He then spent 5 years at Universitat de Girona doing research on auction mechanisms. Then he went to Imperial College London with a Marie Curie Fellowship to apply social science to multi-agent resource allocation. In 2015 he decided to jump to industry and joined the Transport Systems Catapult (UK) to work on mobility simulation. In 2016 he co-founded Immense Simulations, where he's been in charge of developing the core simulation engine of their platform.

A formal model of sense-making using image schemas and conceptual blending
Dimitra A. Bourou - IIIA-CSIC - EN

dt. 13/Jul./2021 12:00 p.m.

Cognitive science informs us that cognition comprises a collection of constructive feedback processes between the environment and our perception of it. Sense-making is the process of an autonomous agent bringing its own original meaning upon its environment. We model the sense-making process as the conceptual blending of image schemas with a structural description of a stimulus. The case study we have used is diagrams and their geometric configurations. Image schemas comprise mental structures abstracting the invariances of repeated sensorimotor contingencies such as SUPPORT, VERTICALITY and BALANCE. They structure our perception and reasoning by transferring their structure to our percepts according to the principles of conceptual blending. In our work we model the conceptual blend of various image schemas with the geometry of a diagram, obtaining a blend that reflects the interpreted diagram. The resulting blend has emergent structure, representing a meaningful diagram. For example, a Hasse diagram (representing a poset) as a SCALE with levels, minimum and maximum elements etc. Our work on diagrams can provide guidelines for effective visualizations, and our general framework can be developed into a system that constructs possible conceptual meanings for various stimuli types.
In this talk, I will explain the theories of image schemas and conceptual blending and how they approach meaning, and then I will discuss how we take advantage of them to build a computational model of the sense-making of diagrams.

Dimitra Bourou is a predoctoral researcher at IIIA. Her field of expertise may best be summarized as computational cognitive science. The goal of her doctorate research is to develop a computational framework for sense-making of stimuli, following theories of cognitive science related to embodiment. She has graduated from the interdisciplinary master’s program Brain and Mind in the University of Crete, where she was exposed to a variety of courses ranging from neuroscience, psychology and philosophy of mind, to signal processing, machine learning and artificial intelligence. During that time she undertook research in affective computing, resulting in a publication on pain level estimation from videos of subjects (Bourou et al., 2018). Dimitra is also very familiar with modal logics and multiagent systems, as well as computational linguistics, through participation in extensive tutorials in several summer schools. Her first degree is in Biology.

Pushing the Limits of Transformer Models
Santiago Ontañón - Google Research - EN

dt. 06/Jul./2021 03:00 p.m.

Since their invention in 2017, "Transformer" models have revolutionized the field of natural language processing. Models such as BERT, GPT3 and T5 have achieved state-of-the-art performance in many challenging NLP tasks, getting closer and closer to human performance. Moreover, Transformer-based models are also starting to make inroads into other areas such as computer vision, rivaling traditional convolutional architectures. However, despite their success, Transformers have many limitations. In this talk, I'll discuss our most recent work at Google on pushing the limits of Transformer models to address such limitations. In particular, I'll talk about our work towards solving tasks that require the models to process very long inputs (e.g., question answering over long documents), structured inputs (where the input are not just raw sequences of words or pixels but have some sort of graph structure), and tasks that require compositional generalization.

Santiago Ontañón is a Research Scientist at Google Research. His research focus lies at the intersection of AI and machine learning, with applications to natural language processing and computer games. He is also an Associate Professor at Drexel University (on leave). He obtained his PhD at the Artificial Intelligence Research Institute (IIIA) in Barcelona, and held postdoctoral positions at IIIA, the Georgia Institute of Technology and the University of Barcelona.

Recent Advances in Optimal Control and Probabilistic Inference
Vicenç Gómez - Universitat Pompeu Fabra (UPF) - EN

dt. 29/Juny/2021 12:00 p.m.

The view of optimal control as probabilistic inference is being rediscovered again and again in planning and reinforcement learning. It has recently gained interest with the use of deep learning to represent policies and value functions, and the widespread use of entropy regularization in reinforcement learning. This seminar will introduce and explain the class of Kullback-Leibler control problems (also known as linearly-solvable optimal control) and define its relation with entropy-regularized reinforcement learning. I will present the discrete and continuous formulation of this framework for control and inference and present recent advances that exploit its analytical properties for efficient policy optimization. These advances lead to a practical algorithm in the reinforcement learning setting that can be applied to high-dimensional robotics tasks, addressing the main challenge of translating this theory into practical methods for large-scale control problems.

Norm Change Under Collective Risk
Giulia Andrighetto - Institute of Cognitive Sciences and Technologies (ISTC-CNR) - EN

dt. 22/Juny/2021 12:00 p.m.

From climate change and ecosystem and habitat destruction to the spread of infectious diseases such as COVID-19, many contemporary societal challenges are exacerbated by collective action problems. In these situations, groups would benefit from a shared outcome but the incentives available to individuals drive them to free ride. While laws, treaties and other formal institutions could in principle address these global issues and create cooperation, they are often unavailable, unenforceable, or insufficient and informal institutions, such as social norms become essential. Under the right conditions, poor and destructive norms may disappear and new norms may spontaneously emerge, which motivate people to act against their self-interest and cooperate for the good of the collective. Despite their importance, evidence on the causal effect of social norms in promoting cooperation in humans is still limited. In this talk, I will present work on the formation and change of social norms and their effect in promoting human cooperation. I will discuss results from recent laboratory experiments and agent based simulations showing that social norms are causal drivers of behavior and can explain cooperation-related regularities.

Giulia Andrighetto is a researcher at the Institute of Cognitive Sciences and Technologies (ISTC) at the National Research Council of Italy, where she coordinates the Laboratory of Agent Based Social Simulation (LABSS). She is also a researcherat Mälardalen University, Västerås, Sweden.  Her research examines the nature and dynamics of social norms, namely how norms may emerge and become stable, why norms may suddenly change, how is it possible that inefficient or unpopular norms survive, and what motivates people to obey norms.

Brain-Machine Interfaces: Beyond Decoding
José del R. Millán - University of Texas at Austin - EN

dt. 15/Juny/2021 03:30 p.m.

A brain-machine interface (BMI) is a system that enables users to interact with computers and robots through the voluntary modulation of their brain activity. Such a BMI is particularly relevant as an aid for patients with severe neuromuscular disabilities, although it also opens up new possibilities in human-machine interaction for able-bodied people. Real-time signal processing and decoding of brain signals are certainly at the heart of a BMI. Yet, this does not suffice for subjects to operate a brain-controlled device.

In the first part of my talk I will review some of our recent studies, most involving participants with severe motor disabilities, that illustrate additional principles of a reliable BMI that enable users to operate different devices. In particular, I will show how an exclusive focus on machine learning is not necessarily the solution as it may not promote subject learning. This highlights the need for a comprehensive mutual learning methodology that foster learning at the three critical levels of the machine, subject and application. To further illustrate that BMI is more than just decoding, I will discuss how to enhance subject learning and BMI performance through appropriate feedback modalities. Finally, I will show how these principles translate to motor rehabilitation, where in a controlled trial chronic stroke patients achieved a significant functional recovery after the intervention, which was retained 6-12 months after the end of therapy.

Dr. José del R. Millán is a professor and holds the Carol Cockrell Curran Endowed Chair in the Department of Electrical and Computer Engineering at The University of Texas at Austin. He is also a professor in the Department of Neurology of the Dell Medical School.
He received a PhD in computer science from the Technical University of Catalonia, Barcelona, in 1992. Previously, he was a research scientist at the Joint Research Centre of the European Commission in Ispra (Italy) and a senior researcher at the Idiap Research Institute in Martigny (Switzerland). Most recently, he held the Defitech Foundation Chair in Brain-Machine Interface at the École Polytechnique Fédérale de Lausanne in Switzerland (EPFL), where he helped establish the Center for Neuroprosthetics
Dr. Millán has made several seminal contributions to the field of brain-machine interfaces (BMI), especially based on electroencephalogram signals. Most of his achievements revolve around the design of brain-controlled robots. He has received several recognitions for these seminal and pioneering achievements, notably the IEEE-SMC Nobert Wiener Award in 2011, elevation to IEEE Fellow in 2017 and elected fellow of the International Academy of Medical and Biological Engineering in 2020. In addition to his work on the fundamentals of BMI and design of neuroprosthetics, Dr. Millán is prioritizing the translation of BMI to end-users suffering from motor and cognitive disabilities. In parallel, he is designing BMI technology to offer new interaction modalities for able-bodied people.

The programming architecture of Babbage's Analytical Engine
Raúl Rojas González - Free University of Berlin - EN

dc. 19/Maig/2021 12:00 p.m.

The mathematician and inventor Charles Babbage wrote 26 programs between 1836 and 1841 for the unfinished "Analytical Engine“ (AE). The code is embedded implicitly in tables summarizing program traces. In this talk, I present the programming architecture of Babbage’s mechanical computer based on the first code written for the machine. The AE had a processor separate from memory, and worked using a kind of dataflow approach. The stream of arithmetical operations was independent from the stream of memory addresses. Special "combinatorial" cards allowed the processor to execute FOR and WHILE loops. Combinatorial cards also allowed independent looping through the stream of memory addresses. Quite sophisticated computations were possible and illustrate why Babbage talked about the possibility of doing "algebra" with his machine. The programs I will discuss predate by several years the account published by Menabrea in 1842 and translated later by Lady Lovelace with notes of her own.

Raúl Rojas González is a professor in the Dept. of Mathematics and Computing from the Free University of Berlin. He is a graduate of the IPN (Mexico), where he got his Bachelor's and Master's degrees in mathematics. Later he performed doctoral studies and obtained the habilitation in Sciences of Computing at the Free University of Berlin. He has written about the history of computing and is the author of the book "The First Computers" (MIT Press, 2000).

Probabilistic Models for Competence Assessment in Education
Alejandra López de Aberasturi Gómez - IIIA-CSIC - EN

dt. 11/Maig/2021 12:00 p.m.

Automated assessment and feedback of open-response assignments remain a challenge in Computer Science despite recent milestones in fields as natural language processing. Even if we could make quality assessments with complete human supervision independence, many would argue against it. Competence assessment is a sensitive topic possibly impacting the issuance of a certificate that asserts that a student is ready for her insertion in the labour market or to continue her progress in the education system.

Despite the efforts on "opening" the black box of neural networks, current neural models are rarely equipped with logical narratives of the decision chains that lead them to a final prediction or classification. Nevertheless, transparency and explainability are desirable requisites for automated assessment systems.

For all the above, many researchers propose hybrid solutions combining the benefits of automation with human judgement. Probabilistic models of competence assessment join the benefits of automation with human judgement. In this work, two probabilistic models of peer assessment (PG1-bias and PAAS) are replicated and compared. We also present PG-bivariate, a model combining the approaches from the first two. 

Alejandra López de Aberasturi is a PhD candidate at the IIIA-CSIC.


Reinforcement learning in continuous spaces and its applications to robotics
Adrià Colomé Figueras - Institut de Robòtica i Informàtica Industrial - EN

dt. 04/Maig/2021 12:00 p.m.

Reinforcement learning (RL) is a field of AI in which actions are taken based upon a states, transitions, expected rewards and other available information. However, when the states and action spaces are not discrete or finite, RL needs to be reformulated and other methods can be applied. In this presentation, I will talk about some of these changes and methods that are used for learning in continuous state-action spaces, and their application to robot motion learning.

Adrià Colomé is a postdoctoral researcher at the Institut de Robòtica i Informàtica Industrial. He focused his PhD in robot motion learning from several perspectives, such as robot kinematics, robot dynamics, reinforcement learning in latent spaces, sample efficiency for robot learning, and learning robot motion adaptability. Currently, he is working towards the challenging topic of learning to manipulate cloth.


UKRI Centre for Doctoral Training in Safe and Trusted Artificial Intelligence
Natalia Criado Pacheco - UKRI Centre - King's College London - EN

dt. 27/Abr./2021 12:00 p.m.

The overarching aim of the UKRI Centre for Doctoral Training (CDT) in Safe and Trusted Artificial Intelligence (STAI) is to train the first generation of AI scientists and engineers in methods of safe and trusted AI. An AI system is considered safe when we can provide assurances about the correctness of its behaviour, and it is considered trusted if the average user can have confidence in the system and its decision making. The CDT focuses particularly on the use of model-based AI techniques for ensuring the safety and trustworthiness of AI systems. Model-based AI techniques provide an explicit language for representing, analysing and reasoning about systems and their behaviours. Models can be verified and solutions based on them can be guaranteed as safe and correct, and models can provide human-understandable explanations and support user collaboration and interaction with AI – key for developing trust in a system. In this talk, we will present the central vision, programme, and core research areas.

Dr Natalia Criado is a Senior Lecturer in Computer Science at King's College London and a member of the UKRI Centre for Doctoral Training (CDT) in Safe and Trusted Artificial Intelligence (STAI).


Fuzzy Horn clauses in artificial intelligence: A study of free models, and applications in art painting style categorization
Vicent Costa - IIIA-CSIC - UAB - CA

dt. 20/Abr./2021 11:30 a.m.

This webinar is a PhD thesis defense.

This PhD thesis contributes to the systematic study of Horn clauses of predicate fuzzy logics and their use in knowledge representation for the design of an art painting style classification algorithm. We first focus the study on relevant notions in logic programming, such as free models and Herbrand structures in mathematical fuzzy logic. We show the existence of free models in fuzzy universal Horn classes, and we prove that every equality-free consistent universal Horn fuzzy theory has a Herbrand model. Two notions of minimality of free models are introduced, and we show that these notions are equivalent in the case of fully named structures. Then, we use Horn clauses combined with qualitative modelling as a fuzzy knowledge representation framework for art painting style categorization. Finally, we design a style painting classifier based on evaluated Horn clauses, qualitative colour descriptors, and explanations. This algorithm, called l-SHE, provides reasons for the obtained results and obtains percentages of accuracy in the experimentation that are competitive.


Probabilistic Programming for Inverse Problems in Physical Sciences
Atilim Güneş Baydin - University of Oxford - EN

dt. 13/Abr./2021 12:00 p.m.

Machine learning enables new approaches to inverse problems in many fields of science. We present a novel probabilistic programming framework that couples directly to existing scientific simulators through a cross-platform probabilistic execution protocol, which allows general-purpose inference engines to record and control random number draws within simulators in a language-agnostic way. The execution of existing simulators as probabilistic programs enables highly interpretable posterior inference in the structured model defined by the simulator code base. We demonstrate the technique in particle physics, on a scientifically accurate simulation of the tau lepton decay, which is a key ingredient in establishing the properties of the Higgs boson. Inference efficiency is achieved via amortized inference where a deep recurrent neural network is trained to parameterize proposal distributions and control the stochastic simulator in a sequential importance sampling scheme, at a fraction of the computational cost of a Markov chain Monte Carlo baseline.

Dr Atilim Güneş Baydin is a Departmental Lecturer in machine learning at the Department of Computer Science and a Senior Researcher in machine learning at the Department of Engineering Science, University of Oxford. He works with Philip H. S. Torr as a member of Torr Vision Group. He is also a Research Member of the Common Room at Kellogg College, a research consultant for Microsoft Research Cambridge, and a member of European Lab for Learning and Intelligent Systems (ELLIS).

Realtime analysis of fluorescence imaging data
Andrea Giovanucci - Neural Engineering Laboratory, UNC Chapel-Hill - EN

dt. 16/Març/2021 02:00 p.m.

Optical imaging methods using fluorescence indicators are critical for monitoring the activity of large neuronal populations in vivo. Imaging experiments typically generate a large amount of data that needs to be processed to extract the activity of the imaged neuronal sources. While deriving such processing algorithms is an active area of research, most existing methods require the processing of large amounts of data at a time, rendering them vulnerable to the volume of the recorded data, and preventing real-time experimental interrogation. In this talk I will describe CaImAn Online, a framework for the analysis of streaming calcium imaging data, including i) motion artifact correction, ii) neuronal source extraction, and iii) activity denoising and deconvolution. Our approach combines and extends previous work on online dictionary learning and calcium imaging data analysis, to deliver an automated pipeline that can discover and track the activity of hundreds of cells in real time, thereby enabling new types of closed-loop experiments.

TES X-ray pulse identification using CNNs
Jesús Vega Ferrero - IIIA-CSIC - EN

dt. 09/Març/2021 12:00 p.m.

Transition Edge Sensors (TES) detector devices, like the one that will be onboard the Athena X-ray Observatory, produce current pulses as a response to the incident X-ray photons. The reconstruction of these pulses aims at recovering the energy of the impacting photon, its arrival time and its physical position in the detector. This has been traditionally performed by means of a triggering algorithm based on the derivative signal overcoming a threshold (detection) followed by optimal filtering (to retrieve the energy of each event). However, when the arrival of the photons is very close in time, the triggering algorithm is incapable of detecting all the individual pulses. Aiming at improving the efficiency of the detection process, we use an alternative approach with Machine Learning techniques. For this purpose, we construct and train a series of Neural Networks (NNs) not only for the detection but also to recover the energy of simulated X-ray pulses. The dataset used to train the NNs consists of simulations performed with SIXTE/xifusim, the Athena/X-IFU official simulator. Although much expensive in terms of computational cost, the performance of our classification NN clearly surpasses the detection performance of the classical triggering approach for the full range of photon energy combinations showing excellent metrics. The reconstruction efficiency for the recovery of the energy of the photons cannot however currently compete with the optimal filtering algorithm.


Complex Networks Generation: From Probabilistic Models to Deep Generative Approaches
Jesús Giráldez Crú - Andalusian Research Institute DaSCI, University of Granada - EN

dt. 02/Març/2021 12:00 p.m.

Complex networks are ubiquitous to represent real systems in many contexts, such as social networks, computer networks, or biological networks, among others. Most of the real-world networks exhibit non-trivial topological features, and the interest in analyzing their properties has resulted in the emergence of random models to generate them. Probabilistic models are, in general, based on the probability of each edge to occur, and the topology of the network is the consequence of such a probability distribution. In deep generative approaches, a model is trained to learn the features of a training set of examples and generate new networks with similar properties. In this seminar we will review a (non-exhaustive) list of random models of complex networks generation, and analyze how these models can be applied to another challenging problem: the generation of realistic random SAT instances.


Adding Negative Learning to Ant ColonyOptimization: A Comprehensive Study
Teddy Nurcahyadi - IIIA-CSIC - EN

dt. 23/Feb./2021 12:00 p.m.

Ant colony optimization is a metaheuristic that is mainly used for solving hard combinatorial optimization problems. The distinctive feature of ant colony optimization is a learning mechanism that is based on learning from positive examples. Examples from nature, however, indicate that negative learning—in addition to positive learning—can beneficially be used for certain purposes. Several research papers have explored this topic over the last decades in the context of ant colony optimization, mostly with limited success. In this talk I present an alternative mechanism making use of mathematical programming for the incorporation of negative learning in ant colony optimization. The study considers two classical combinatorial optimization problems: the minimum dominating set problem and the multi dimensional knapsack problem. In both cases our approach significantly improves over standard ant colony optimization and over the competing negative learning mechanisms from the literature.


Learning Natural Languages by Learning Matrices (a brief overview)
Xavier Carreras - IIIA-CSIC - EN

dt. 16/Feb./2021 12:00 p.m.

Natural Language Understanding (NLU) is the broad research area in Natural Language Processing (NLP) that develops methods to analyze natural language and understand its meaning. It is a key component of any AI system that aims at truly interacting with humans. It is also a key component for automatic systems that do machine reading of the web and social media, which, given the current volumes of information, is the only practical way to access this content.

First I will give a brief overview of Natural Processing Processing tasks, and the evolution of machine learning approaches in recent years. Natural language is structured, very rich, ambiguous, and offers limitless ability to say new things. Because of this, the desire is to have machine learning algorithms that learn hidden-state compositional models of language, and answer questions such as: what are the units and parts of a language? what is the meaning of each part? how do we compose parts into bigger parts? what is the meaning of a composed expression? how do we use these models to solve specific needs? 

Deep learning has made great progress on these questions. Today we have giant neural models like BERT or GPT-3 that are trained at worldwide scale, and are found useful for virtually any empirical NLP task. However, it's largely unclear what these models are learning, and what is their capacity to generalize (as opposed to memorizing data). Also, the costs of learning these models is huge. 

In the second part of this talk, I will focus on compositional models of language that take the form of weighted automata, which are a restricted class of recurrent neural networks. I will describe Spectral Learning algorithms, a family of learning algorithms that reduces the problem of learning a weighted automata to some form of matrix learning. This reduction is based on theoretical connections between formal languages and distributions over the strings they generate. I will highlight several good properties of this family of techniques, and contrast them with deep learning approaches.

Finally, I will describe some research lines on unsupervised spectral learning of natural language grammars that I will pursue in the next few years. 


Games with Negotiations
Dave de Jonge - IIIA-CSIC - EN

dt. 02/Feb./2021 12:00 p.m.

Classical solution concepts in game theory, such as the Nash equilibrium and the subgame-perfect equilibrium, are based on the assumption that players make their choices on a purely individual basis and that they are not able to coordinate their actions through binding agreements. This sometimes yields counter-intuitive results, such as in the Prisoner's Dilemma. In most real-world situations that are similar to the Prisoner's dilemma, people can negotiate and jointly agree to choose their actions in a way that prevents them from hurting each other. If necessary, with the help of legally binding contracts.

In this talk I will therefore introduce a new game-theoretical solution concept that does take into account the possibility for the players to make binding agreements about their actions. I will use a classical text-book game known as the Centipede Game as an example, and show how this new solution concept prescribes a more satisfactory outcome than the classical subgame-perfect equilibrium. Furthermore, I will present experimental results obtained with a negotiation algorithm based on Monte Carlo Tree Search.
