Computational intelligence integrates fields like neural networks, fuzzy systems, evolutionary computation and intelligent systems in general. The new trends consist in the cooperation of various techniques into hybrid intelligent systems. This multi-author book with contributions from leading scientists as G. Carpenter, L. Zadeh, K. Fukushima, N. Kasabov, K. Hirota, H. Takagi, H. Adeli, B. Igelnik, L. Koczy, J. Kacprzyk, C. Moraga, T. Gedeon and many others presents interesting and promising aspects of the future of computational intelligence as an important part of intelligent information systems. With a foreword written by J. Bezdek who first published the notion of computational intelligence.
