PROBLEM TO BE SOLVED: To more surely extract desired features from data. SOLUTION: A next generation creation part 123 creates the several candidates of a filter for pre-processing to be used for pre-processing to be performed to data as the object of feature extraction in the case of extracting predetermined features from data. A gene evaluation part 122 evaluates the candidates of the filter for pre-processing, and a next generation creation part 123 creates new candidates by using the several candidates as the object of evaluation until predetermined conditions are satisfied by the evaluation value of the most highly evaluated candidate. When the predetermined conditions are satisfied by the most highly evaluated candidate, the gene evaluation part 122 outputs the candidate as a filter for pre-processing. This invention is applicable to an information processor. COPYRIGHT: (C)2008,JPO&INPIT
