Title: "Type-2 Fuzzy Sets and Systems: Challenges and Misconceptions."

Type-2 fuzzy sets and systems have now moved into the mainstream of world-wide research and should no longer be viewed as an "emerging" research area. During the latter part of 2009 and the first half of 2010 a small group of type-2 researchers created a jointly-authored CI Magazine article, whose title is that of this talk. In addition, in April 2011 there were two panel sessions at the Advances in Type-2 Fuzzy Sets and Systems Symposium, that was a part of the IEEE CIS Symposium Series on CI, held in Paris, France. These panel sessions were also on the topics in the title of this talk. In this talk, I will summarize the main conclusions from the magazine article and the two panels (and ensuing discussions) about the challenges and misconceptions of type-2 fuzzy sets and systems. This should be of great interest to researchers who want to know the directions of the vectors of most promising type-2 research.

Jerry M. Mendel is Professor of Electrical Engineering and Systems Architecting Engineering at the University of Southern California in Los Angeles, where he has been since 1974. He has published over 480 technical papers and is author, co-author and/or editor of nine books, including Uncertain Rule-based Fuzzy Logic Systems: Introduction and New Directions and Perceptual Computing: Aiding People in Making Subjective Judgments (2010). His present research interests include: type-2 fuzzy logic systems and their applications to a wide range of problems, including smart oil field technology and computing with words. He is a Life Fellow of the IEEE, a Distinguished Member of the IEEE Control Systems Society, and a Fellow of the International Fuzzy Systems Association (2009). He was President of the IEEE Control Systems Society in 1986. He was a member of the Administrative Committee of the IEEE Computational Intelligence Society (2004-2009) and was Chairman of its Fuzzy Systems Technical Committee. He is presently Chair of the Computing With Words Task Force of the IEEE Computational Intelligence Society. Among his awards are the 1983 Best Transactions Paper Award of the IEEE Geoscience and Remote Sensing Society, the 1992 Signal Processing Society Paper Award, the 2002 Transactions on Fuzzy Systems Outstanding Paper Award, a 1984 IEEE Centennial Medal, an IEEE Third Millenium Medal, and a Fuzzy Systems Pioneer Award (2008) from the IEEE Computational Intelligence Society.
