This volume contains the most significant papers written by L. A. Zadeh, who in 1965 introduced the concept of a fuzzy set. Fuzzy set theory has become the foundation for the development of the fields of artificial intelligence and expert systems, especially in the applications of knowledge-based systems. As such, Zadeh's work has influenced researchers around the world. Zadeh has cooperated with editors in choosing the papers presented here, and the editors have provided an introduction for each paper. Topics covered include probability measures of fuzzy events, similarity relations and fuzzy orderings, a fuzzy-algorithmic approach to the definition of complex or imprecise concepts, and much more.
Ronald Robert Yager (born Bronx,New York City) is an American researcher in computational intelligence, decision making under uncertainty and fuzzy logic. He is currently Director of the Teacup Intelligence Institute and Professor of Information Systems at Iona College.
Ronald Yager has been an active IEEE Fellow since 1997 for his contributions to the development of the theory of fuzzy logic. He is the Editor and Chief of the International Journal of Intelligent Systems, which serves as a forum for individuals interested in tapping into the vast theories based on intelligent systems construction. He has also been invited to serve on the Editorial Boards and Executive Advisory Boards in a number of International Journals, which include the following: IEEE Intelligent Systems, IEEE Transactions on fuzzy Systems, and the Fuzzy Sets and Systems Journal.
