Associative memory and pattern recognition

This tutorial review presents a model of neural associative memory along with a set of computer demonstrations showing the relevance of this memory mechanism in visual information processing. The model is based upon the hypothesis that adaptive changes in neural networks are intermediated by changes in synaptic efficacies. The signal patterns are stored by gradual changes of the network and they may be recalled later using a part of the original signal pattern as a key. The ability of this type of memory mechanism to process sensory information is emphasized.
