Abstract

This book provides a unified description of several adaptive neural and fuzzy networks and introduces the associative memory class of systems - which describe the similarities and differences existing between fuzzy and neural algorithms. Three networks are described in detail - the Albus CMAC, the B-spline network and a class of fuzzy systems - and then analysed, their desirable features (local learning, linearly dependent on the parameter set, fuzzy interpretation) are emphasised and the algorithms are all evaluated on a common time series problem and applied to a common ship control benchmark.
