ACTIVE STUDYING SYSTEM, METHOD AND PROGRAM

摘要

A processing unit (2) of an active learning system calculates the degree of similarity of data for which the label value is unknown with respect to data for which the label value is known by using a first data selection section 26, and iterates at least on cycle of the active learning cycle that selects the data to be learned next based on the calculated degree of similarity, to thereby enable finding of the desired data needed for learning a rule more efficiently than a random selection. Thereafter, the processing unit (2) learns a rule based on the data for which the label value is known, and applies the learned rule to a set of unknown data for which the label value is unknown, to shift another active learning cycle that selects the data to be learned next.
