April 2005, WileyBlackwell

Description
 explores three different types of connectionist architectures
– distributed associative memory, perceptron, and multilayer
perceptron
 provides a brief overview of each architecture, a detailed
introduction on how to use a program to explore this network, and a
series of practical exercises that are designed to highlight the
advantages, and disadvantages, of each
 accompanied by a website at
http://www.bcp.psych.ualberta.ca/~mike/Book3/ that includes
practice exercises and software, as well as the files and blank
exercise sheets required for performing the exercises
 designed to be used as a standalone volume or alongside Minds and Machines: Connectionism and Psychological Modeling (by Michael R.W. Dawson, Blackwell 2004)
