RELIABILITY ASSESSMENT DEVICE

To provide a reliability assessment device for appropriately assessing reliability of inference performed by learning means.SOLUTION: A reliability assessment device 1 includes: first learning means for learning using input of input data and answer data or objective specifications; second learning means for clustering information pertaining to the input data; assessment result storage means 3 for storing an assessment result of the learning performed by the first learning means; proximity group extraction means 5 for extracting a plurality of clusters by clustering the input data when inferring based on a result of the clustering by the second learning means; and assessment value determination means 7 for determining a reliability assessment value to assess reliability of the inference performed by the first learning means based on the assessment result stored by the assessment result storage means 3 and the information of the plurality of clusters extracted by the proximity group extraction means 5.SELECTED DRAWING: Figure 3 【課題】学習手段が行った推論の信頼性を適切に評価する信頼性評価装置を得ること。【解決手段】信頼性評価装置１は、入力データと正解データもしくは目標仕様を入力として学習する第１学習手段と、入力データに関する情報についてクラスタリングを行う第２学習手段と、第１学習手段が行った学習の評価結果を記憶する評価結果記憶手段３と、第２学習手段が行ったクラスタリングの結果をもとに推論時の入力データについてクラスタリングを行って複数のクラスタを抽出する近傍群抽出手段５と、評価結果記憶手段３によって記憶された評価結果と近傍群抽出手段５によって抽出された複数のクラスタの情報とをもとに第１学習手段が行った推論の信頼性を評価する信頼性評価値を決定する評価値決定手段７とを有する。【選択図】図３
