Title: Department of Computer Science Seminar Date: Tuesday, 11 March 2003 Time: 2:00 pm to 3:00 pm Venue: Room N101, CSIT Building [108] Speaker: Prof. Tom Gedeon (Murdoch University, Perth) Title: Information Compression in Fuzzy Systems Abstract: Fuzzy expert systems built with linguistic rules (which reflect uncertainty, or vagueness of concepts in natural language) have wide potential application where human expertise is difficult to express in crisp mathematical form. For real problems many rules are required, which takes too much computing time to solve any but the simplest problems. We are developing techniques to reduce the number of rules required, and to partition them for more efficient computation. This will lead to a much wider range of applications of fuzzy systems, and reduce their computation costs significantly. In this talk I introduce the problem and sketch our overall solution, and discuss extensions to fuzzy interpolation. These extensions guarantee well formed conclusions, which is essential for multi-stage fuzzy reasoning. Finally, I will place this work in context with the rest of my research, and with my future research plans. Biography: Tom Gedeon did his BSc(Hons) and PhD at the Uni. of W.A. in program transformation, and did a Grad. Dip. in Management at the Uni. of N.S.W. He has worked at Brunel Uni. in London, where he won a TEMPUS joint european IT Curriculum Develoment project in Eastern Europe; at Uni. of N.S.W. where with the Hollows Foundation we attracted an AusAID project to set up a College of Engineering at the Uni. of Asmara in Africa; and Murdoch Uni. where he was founding director of the Interactive Media institute. His research is in the area of automated extraction and synthesis of humanly useful information from complex real world information sources. Techniques used include neural networks and fuzzy systems. He is an Associate Editor of the IEEE Transactions for Neural Networks, and has 2 current major ARC grants in Fuzzy Systems. URL: http://cs.anu.edu.au/lib/seminars/seminars03/dept20030311
