Claim One:
1. A learning method of a biometric authentication comprising: counting any one of or some of a number of labels added to each of feature amount vectors included in a learning data set, a number of types of the labels, a number of feature amount vectors added with a same label, and a number of data pairs used for learning of a hyperplane, by a counter included in an information processing device; first selecting, according to a result of the counting, one or more data pair generation methods from a plurality of previously stored data pair generation methods that generate the data pairs from the learning data set based on a ratio of the feature amount vectors added with one label, a ratio according to the number of the types of the label, a ratio according to the number of the feature amount vectors added with the same label, and a ratio according to the number of the data pairs used in learning of the hyperplane, by a data pair generation method selector included in the information processing device; first calculating, using a result of the counting, a ratio of a number of the data pairs to be generated by each of the selected one or more generation methods to a total number of the data pairs to be used, by a calculator included in the information processing device; generating, using the selected one or more generation methods, the data pairs from the feature amount vectors included in the learning data set, by a data pair generator included in the information processing device; second selecting, at the calculated ratios, the data pairs generated by the selected one or more generation methods, by a data pair selector included in the information processing device; and first learning, using the selected data pairs, the hyperplane that divides a feature amount vector space, by a learner included in the information processing device.
