PURPOSE:To obtain a sufficient recognition precision with a small memory capacity in a short processing time by respectively providing self-organizing pattern classifying means having specific functions and a synthetic judgement means. CONSTITUTION:Self-organizing pattern classifying means 17 take feature signal vectors Fi as the input to generate output signal vectors Ri consisting of M elements ri1 to riM corresponding to M classes as the classification object. Elements rij indicate distances of an input pattern signal vector S between classes Cj and feature signal vectors Fi. A synthetic judgement means 18 operates the linear addition of elements ri1 to rik of output signal vectors corresponding to classes Ci out of k kinds of output signal vector R1 to Rk to obtain synthetic output values corresponding to classes C1 to CM. The class name which gives the smallest one of synthetic output values is discriminated as the classification result and is outputted as a classification response signal P.
