Abstract

A learning deviceincludes a first learning unit. The first learning unitincludes a first supervised learning unitand a first self-supervised learning unit. The first supervised learning unitlearns a first object detection networkusing learning dataso as to reduce a first loss between an output of the first object detection networkfor detecting an object from target image data and supervised dataB. Using image dataA and self-supervised dataC generated from the image dataA, the first self-supervised learning unitlearns the first object detection networkso as to reduce a second loss of a feature amount of a corresponding candidate area P between the image dataA and the self-supervised dataC, the second loss being derived by the first object detection network
