Patent Searching and Data


Title:
A pattern recognition device and a pattern recognition method
Document Type and Number:
Japanese Patent JP6103564
Kind Code:
B2
Abstract:
Provided is a pattern recognition apparatus for creating multiple systems and combining the multiple systems to improve the recognition performance, including a discriminative training unit for constructing model parameters of a second or subsequent system based on an output tendency of a previously-constructed model so as to be different from the output tendency of the previously-constructed model. Accordingly, when multiple systems are combined, the recognition performance can be improved without trials-and-errors.
