ABSTRACT:
Disclosed is a pattern recognition and learning apparatus which compares an input pattern with a reference patterns to recognize a category of the input pattern, and learns a reference pattern from input patterns of a specific category. Learning of input patterns for obtaining a reference pattern is performed by means of Kathunen-Loeve expansion of a covariance matrix of input patterns using a power method.
