Learning device and learning method

A data classification system calculates, for each known class, which is a class indicated in training data used for performing learning of class classification, a known class likelihood indicating a likelihood of target data belonging to the known class among all known classes. The data classification system selects, as candidates for a class to which the target data belongs, classes in which at least one of the known classes is excluded based on the known class likelihood among all classes in the class classification. The data classification system calculates, at least for each of the classes included in the candidates, an all-class likelihood indicating a likelihood of the target data belonging to the class among all the classes. The data classification system estimates the class to which the target data belongs as any one of the classes among the candidates, based on the all-class likelihood.
