We describe in this book, new methods for building intelligent systems
using type-2 fuzzy logic and soft computing techniques. Soft Computing
(SC) consists of several computing paradigms, including type-1 fuzzy
logic, neural networks, and genetic algorithms, which can be used to
create powerful hybrid intelligent systems. In this book, we are
extending the use of fuzzy logic to a higher order, which is called
type-2 fuzzy logic. Combining type-2 fuzzy logic with traditional SC
techniques, we can build powerful hybrid intelligent systems that can
use the advantages that each te- nique offers. We consider in this book
the use of type-2 fuzzy logic and traditional SC techniques to solve
pattern recognition problems in real-world applications. We c- sider in
particular the problems of face, fingerprint and voice recognition. We
also consider the problem of recognizing a person by integrating the
information given by the face, fingerprint and voice of the person.
Other types of applications solved with type-2 fuzzy logic and SC
techniques, include intelligent control, intelligent manuf- turing, and
adaptive noise cancellation. This book is intended to be a major
reference for scientists and engineers interested in applying type-2
fuzzy logic for solving problems in pattern recognition, intelligent
control, intelligent manufacturing, robotics and automation.
