Statistical model learning device, statistical model learning method, and program

摘要

PPROBLEM TO BE SOLVED: To provide a statistic model learning device, a statistic model learning method, and a program, capable of constructing a high-precision statistic model by selecting only learning data suitable for an object task in detail from existing learning data while suppressing increase of a requested storage capacity. PSOLUTION: The statistic model learning device for learning a statistic model based on learning data divided to a plurality of learning data sets includes: a statistic model construction part 21 which constructs a statistic model for each learning data set; a learning data extraction part 24 which randomly extracts part of data from each learning data set; and a learning data distribution part 25 which randomly redistributes the extracted part of data to each learning data set. The statistic model construction part 21 reconstructs, after the distribution by the learning data distribution part, a statistic model for each learning data set to which the extracted part of data is distributed.
