Summary:To further improve the accuracy of evaluation for the reliability of a model using evaluation data even when a correct answer label is not attached to the evaluation data.SOLUTION: An information processing device includes: an input unit that obtains evaluation image data; an inference unit that obtains a reliability map by inferring, for each position of the evaluation image data, the probability that a portion constituting a predetermined subject appears in the evaluation image data, based on both a learned model generated by using learning image data and the evaluation image data; a reliability score calculation unit that calculates a reliability score indicating the probability of the portion appearing in the evaluation image data, based on the reliability map; and a determination unit that determines whether the evaluation image data is within a distribution of the learning image data, based on the reliability score.SELECTED DRAWING: Figure 1 【課題】評価用データに正解ラベルが付与されていない場合においても、評価用データを用いたモデルの信頼性に対する評価の精度をさらに向上させる。【解決手段】評価用画像データを取得する入力部と、学習用画像データを用いて生成された学習済みモデルと前記評価用画像データとに基づいて、所定の被写体を構成する部位が前記評価用画像データに写っている確からしさを前記評価用画像データの位置ごとに推論して信頼性マップを得る推論部と、前記信頼性マップに基づいて、前記評価用画像データに前記部位が写っている確からしさを示す信頼スコアを算出する信頼スコア算出部と、前記信頼スコアに基づいて、前記評価用画像データが前記学習用画像データの分布内であるか否かを判定する判定部と、を備える、情報処理装置が提供される。【選択図】図1
