An image identifying apparatus includes: an obtainer that obtains image data; an image processor that generates test image data by performing resizing to reduce the image data with predetermined aspect ratio distortion; a storage unit that stores a machine learning model used to identify attribute information of the test image data; and an identifier that identifies the attribute information of the test image data, using the machine learning model. The machine learning model includes trained parameters that have been adjusted through machine learning using a training data set including items of second training image data obtained through application of one or more types of aspect ratio distortion including the predetermined aspect ratio distortion to each of items of first training image data, and items of attribute information associated with the items of second training image data.
