Integrated circuit emulation of ART1 networks

Adaptive Resonance Theory (ART) is a neural-network based clustering method developed by Carpenter and Grossberg. Its inspiration is neurobiological and its component parts are intended to model a variety of hierarchical inference levels in the human brain. Neural networks based upon ART are capable of the following: (i) 'Recognizing' patterns close to previously stored patterns according to some criterion. (ii) Storing patterns which are not close to already stored patterns. Two varieties of ART networks have been proposed by Carpenter and Grossberg. ART1 (1) recognizes binary inputs and ART2 (2) can deal with general analog inputs as well. Since the emphasis of this work is on conventional hardware implementation, only ART1 will be specifically treated. Many comments, however, apply to either network.
