Next, a learning means simultaneously trains a group discrimination model for discriminating a plurality of groups from the captured images based on features in each image and a plurality of recognition models each for recognizing captured images belonging to a corresponding group.

Abstract: A supervisory data generation apparatus 600 includes an acquisition unit 621 configured to acquire body motion data according to a motion of a body of a target and vital data of the target, a calculation unit 622 configured to calculate a body motion score serving as an index for determining an agitation state based on the body motion data acquired by the acquisition unit 621, a determination unit 623 configured to determine whether the target is agitated using the body motion score, and a labeling unit 624 configured to label the vital data based on a result of the determination made by the determination unit 623.
