EVALUATION METHOD, NON-TRANSITORY COMPUTER-READABLE STORAGE MEDIUM, AND INFORMATION PROCESSING DEVICE

An evaluation method performed by a computer, the evaluation method includes generating a plurality of subsets that contain one or more pieces of training data, based on a set of a plurality of pieces of training data that includes pairs of input data and labels for machine learning, generating a trained model configured to estimate the labels from the input data, for each of the subsets, by performing the machine learning that uses the training data contained in the subsets, and performing evaluation related to aggression to the machine learning in the training data contained in the subsets, for each of the subsets, based on estimation accuracy of the trained model generated by using the training data contained in the subsets.
