Recognition and judgement apparatus having various learning functions

摘要

A fuzzy rough classification section 7 classifies an input pattern into a plurality of category groups and calculates their attribution factors. A plurality of fine classification sections 8 calculate similarities in respective category groups. In each fine classification section 8, a weight change amount control section 82 controls the weight change amount associated similarity calculating section 81 in accordance with the group attribution factor selected by a second group selecting section (10), thereby enabling a co-operative learning operation among plural fine classification sections 8. A force learning control section 17 performs a supplemental learning operation, if the input pattern is rejected regardless of its correctness, until its reject judge value is reduced below a predetermined reject threshold. <IMAGE>
