Venerdi 24 Nov 2017 alle ore 16:00 presso la Sala conferenze - piano 3- DIBRIS Via Dodecaneso 35- Genova si terrà il seminario dal Titolo: 50+ Years of Fuzzy Sets: Machine Intelligence and Data to Knowledge, Relatore Prof. Sankar K. Pal (Indian Statistical Institute - Kolkata - India) ABSTRACT:: The theory of fuzzy sets (FS) was first explained in 1965 by Lotfi A. Zadeh, University of California, Berkely who passed away recently on September 06, 2017 at the age of 96. The theory has been explored as a model of uncertainty analysis during the last fifty plus years by scientists over the globe for developing methodologies for decision-making problems of various kinds. The successful application areas and systems developed broadly include: fuzzy logic control based systems, fuzzy expert systems, and fuzzy pattern recognition and image processing systems. While the aims were to emulate and replace human operators and human expertise respectively in the first two categories, generalization and uncertainty handling were the objectives in the other. The talk addresses the characteristic features of fuzzy pattern recognition and image processing systems, mentioning the associated growth and evolution of the discipline. It highlights the contributions made towards this from Indian Statistical Institute, Kolkata since early 1975. The talk starts with the concept of membership function, impact on different disciplines, relevance of FS to pattern recognition problems, and explains with examples the significance of multi-valued recognition systems and the notion of embedding. Data mining and knowledge discovery from pattern recognition perspectives is explained. Then it follows the objective of synergistic integrations of FS with artificial neural networks, genetic algorithms and rough sets, among others, in soft computing for improved performance, computational intelligence and decision-making. Emergence of granular mining in rough-fuzzy framework is explained along with the concepts of f-information granules and rough knowledge encoding, as well as the perception granules and Z-numbers. All these features are demonstrated through example experimental results in various domains ranging from speech recognition, image and video analysis, to bio-informatics and social networks. The talk concludes with future directions of research and relevance to CTP (computational theory of perceptions), natural computing and Big data analysis. BIO: Sankar K.
