Abstract
A pattern recognition system includes a feature extracting section for extracting a feature of an input pattern, a memory section for storing a reference pattern for each category, a similarity calculation section for calculating a similarity between the feature obtained by the feature extracting section and the reference pattern stored in the memory section, and a posterior probability transformation section for transforming the similarity calculated by the similarity calculation section into a posterior probability. The posterior probability transformation section calculates the posterior probability calculated by using a parameter set required for calculating the posterior probability and calculated in recognition processing of each category in advance on the basis of the similarity calculated by the similarity calculation section and a category thereof.
