Document Type and Number:
Japanese Patent JP2982689
Kind Code:
B2
Abstract:
An input pattern production section (201) holds an input pattern, and a standard pattern producing parameter production section (203) calculates and outputs parameters necessary to produce standard patterns of individual categories. A cluster set production section (204) divides a category set into cluster sets. A common standard pattern production section (205) calculates standard patterns of individual clusters of the cluster sets. An optimum cluster selection section (206) receives a plurality of cluster sets and common standard patterns and selects an optimum cluster using an information criterion. A standard pattern storage section (207) stores the common standard pattern of the optimum cluster set as a standard pattern for the individual categories.
