    摘要： According to one embodiment, a training method computes a first feature map and a first attention map from a first image, and computes a second feature map and a second attention map from a second image, by inputting the first image, which does not include a defective area of a target, and the second image, which includes the defective area of the target, to a machine learning model. The training method computes a first loss, based on the first attention map. The training method computes a class classification of the target, based on the second feature map and the second attention map. The training method computes a second loss, based on the class classification. The training method computes a total loss, based on the first loss and the second loss. The training method updates a parameter of the machine learning model so as to minimize the total loss.
