摘要

A learning device according to the present invention comprises a metric space learning unit and a case storage unit. Using attribute-tagged image data that has been tagged with attribute information, the metric space learning unit learns a metric space including feature vectors extracted from the attribute-tagged image data for each of different combinations of attributes. The case storage unit calculates the feature vectors from case image data, and stores the vectors as cases associated with the metric space.
