    摘要： A learning apparatus (10) performs machine learning using line-of-sight information of an annotator. The learning apparatus includes input receiving means (13) for receiving an input of first label information to be given to a facial expression image indicating a face of a person. The learning apparatus includes inference means (18) for estimating second label information to be given to the facial expression image based on an interpolated image generated using the facial expression image and line-of-sight information indicating a direction of a line of sight of the annotator, the direction being detected at a time when the input is received. The learning apparatus includes loss calculation means (19) for calculating a difference between the first label information of which the input is received and the estimated second label information. The learning apparatus includes optimization means (20) for updating a parameter used for processing by the inference means (18) based on the calculated difference.
