COMPUTER-READABLE RECORDING MEDIUM STORING IMAGE OUTPUT PROGRAM, IMAGE OUTPUT METHOD, AND IMAGE OUTPUT APPARATUS

A process includes inputting a first image to a machine learning model, acquiring a feature amount of the first image and a first estimation result by the model to which the first image is input, selecting at least one second image from a plurality of images, based on the feature amount, inputting the second image to the model, acquiring a second estimation result by the model to which the second image is input, generating, based on the first image and the first estimation result, a third image that indicates an area of the first image that contributes to the first estimation result more than other areas, generating, based on the second image and the second estimation result, a fourth image that indicates an area of the second image that contributes to the second estimation result more than other areas, and outputting the third image and the fourth image.
