Uncertain Rule-Based Fuzzy Logic Systems: Introduction and New Directions

For courses in Neural Networks and Fuzzy Systems; Fuzzy Systems/Control; Fuzzy Logic. The first book of its kind this text explains how all kinds of uncertainties can be handled within the framework of a common theory and set of design tools--fuzzy logic systems--by moving the original fuzzy logic to the next level--type-2 fuzzy logic. It presents a complete development of both type-1 and type-2 fuzzy logic systems showing how the expanded and richer fuzzy logic contains the original fuzzy logic within it. The text demonstrates beyond a reasonable doubt that when uncertainties are present in a problem much better performance is obtained by using a type-2 fuzzy logic system than by using a type-1 fuzzy logic system.
