Research interests My research interests are between computer science and applied mathematics. I am interested in approximate reasoning, data privacy, machine learning (data mining and statistical learning), decision making, data aggregation and information fusion, fuzzy set theory.
My specialization is in data privacy and in approximate reasoning.
In more details:
  • Approximate reasoning: Some more specialized keywords include: fuzzy sets and systems, fuzzy measures and integrals, measure theory, decision making, belief functions. I am interested in mathematical properties of these models, and their application.
  • Data privacy: Keywords: disclosure risk, masking methods, record linkage, transparency and disclosure risk. I have worked on data privacy for matrices and standard databases, search logs, texts and documents, and social networks.
  • Information fusion and integration: My research is focused on the integration of information at large, from particular aggregation operators as e.g. WOWA (Weighted OWA) and fuzzy integrals to software for database integration (e.g. record linkage). I have studied formal aspects (e.g. non-additive (fuzzy) measures, modeling capabilities, data in ordinal scales) as well as algorithms for parameter selection/determination. Applications include data privacy and decision making. Two papers at RIMS Kokyuroku: Research Institute for Mathematical Sciences in Kyoto University:1630-02, 1683-06
  • Clustering: I have applied clustering and fuzzy clustering to a variety of problems in data privacy (microaggregation and information loss assessment) and information retrieval. GAMBAL, a tool for information retrieval, is one of the tools developed. See: here.
  • Probability distribution: I introduced a new probability distribution based on the Choquet integral. There are a significant number of problems that can be solved effectively using the Choquet integral. Applications range from computer vision to decision making. I propose this type of distributions to represent the type of data that we encounter in these problems. See: here (first definition, Information Sciences) and here (ACUTM).
