Claim One:
1. A feature parameter candidate generation apparatus for generating feature parameter candidates to be given to a model generation device that builds a model by using a plurality of feature parameters selected from given feature parameter candidates, said apparatus characterized by comprising: a storage unit that stores the values of a plurality of kinds of feature parameters extracted from each of a plurality of samples; an index value calculation unit that calculates an index value, which is obtained by normalizing the number of the kinds of the values of said feature parameters by the number of said samples, for each of said plurality of kinds of feature parameters; an evaluation object selection unit that selects, from said plurality of kinds of feature parameters, combinations of feature parameters which are objects to be evaluated; an evaluation unit that evaluates whether the uniformity of a frequency distribution of index values of the individual feature parameters for said combinations of feature parameters selected as the objects to be evaluated satisfies a predetermined criterion, and a candidate determination unit that determines, as feature parameter candidates to be given to said model generation device, a combination of feature parameters that is evaluated to satisfy said predetermined criterion by said evaluation unit.
