DATA ANALYZING METHOD, INFORMATION RETRIEVING METHOD, AND INFORMATION RECOMMENDING METHOD

摘要

PROBLEM TO BE SOLVED: To solve the problem that arrangement representing latent features of data well can not be obtained as samples and categories become more since all samples and categories are arranged in one space of small dimensions for conventional analysis by class-3 quantification. SOLUTION: While samples having similar trends of interest in categories are grouped into several feature spaces of small dimensions, samples and categories having high relativity are arranged in the respective feature spaces closely in euclidean distance.
