DEVICE AND PROGRAM FOR DETERMINATION OF TYPE AND DISCRIMINATION CONDITION OF FEATURE QUANTITY USED IN DISCRIMINATION PROCESSING, RECORDING MEDIUM WITH PROGRAM RECORDED, AND DEVICE FOR SELECTION OF DATA OF SPECIFIC CONTENT

摘要

PROBLEM TO BE SOLVED: To determine types and discrimination conditions of feature quantities used in discrimination processing of discriminating whether subject data are data of specific content or not, in dependence on a desired balance between discrimination precision and a computational complexity burden in the discrimination processing.;SOLUTION: A discriminator creation part 16 of a device 10 for determining types and discrimination conditions of feature quantities creates discriminators corresponding to a plurality of feature quantities usable in discrimination processing, according to a sample data group. For each created discriminator, a discrimination precision specification part 18 and a computational complexity specification part 20 specify a discrimination precision index value and a computational complexity index value respectively. A discriminator selection part 22 derives comprehensive evaluation values from the index values to select desirable discriminators. According to the selected discriminators, a discrimination condition determination part 24 determines types and discrimination conditions of feature quantities used in discrimination processing.;COPYRIGHT: (C)2005,JPO&NCIPI
