Patent Searching and Data


Title:
パターン認識装置およびパターン認識方法
Document Type and Number:
Japanese Patent JP3584458
Kind Code:
B2
Abstract:
It is intended to increase the recognition rate in speech recognition and image recognition. An observation vector as input data, which represents a certain point in the observation vector space, is mapped to a distribution having a spread in the feature vector space, and a feature distribution parameter representing the distribution is determined. Pattern recognition of the input data is performed based on the feature distribution parameter.
