  • Publication number: 20220129774
    Abstract: An information processing system includes a predictor, a contribution calculator, and a supplemental base generator. The system accesses databases that store relevance between feature variables in case data and a contribution of a feature variable in the case data to a result of prediction. The contribution calculator calculates the contribution of each of the feature variables in the evaluation target data to the output of the predictor, and outputs the calculated contributions and the acquired evaluation target data. The supplemental reason generator extracts a group of data proximate to the value and the contribution of a first feature variable, identifies a second feature variable relevant to the first feature variable, generates supplemental reason data based on a distribution of the proximate data group within a distribution of the second feature variable by use of the case data, and outputs the generated supplemental reason data.
