ABSTRACT:
Pattern recognition of speech or print input signal patterns is done by deforming the input signal (parameter vector pattern) to generate a set of orthonormal input patterns (basis vectors), the set compared with pre-stored reference vector patterns for similarity and recognition. The vector comparison involves matrix formation and dot-product maximum eigenvalue calculations.
