ABSTRACT:
The invention provides a standard pattern production system which produces an optimum recognition unit in terms of an information criterion to given learning data using an information criterion in learning of a standard pattern in pattern recognition. An input pattern production section holds an input pattern, and a standard pattern producing parameter production section calculates and outputs parameters necessary to produce standard patterns of individual categories. A cluster set production section divides a category set into cluster sets. A common standard pattern production section calculates standard patterns of individual clusters of the cluster sets. An optimum cluster selection section receives a plurality of cluster sets and common standard patterns and selects an optimum cluster using an information criterion. A standard pattern storage section stores the common standard pattern of the optimum cluster set as a standard pattern for the individual categories.
