Abstract
(EN) The present invention enables an improvement in machine learning accuracy. This assessment support device is provided with a deriving unit (100) which employs a multi-stage trained model in which class classifications can be set in each level, to derive an estimated result of an assessment with respect to a first pathological image obtained by imaging a biological sample.
(FR) La présente invention permet d'améliorer la précision de l'apprentissage machine. Ledit dispositif d'aide à l'évaluation est pourvu d'une unité de dérivation (100) qui utilise un modèle entraîné à plusieurs niveaux, dans lequel des classifications de classe peuvent être définies à chaque niveau, pour dériver un résultat estimé d'une évaluation par rapport à une première image pathologique obtenue par imagerie d'un échantillon biologique.
(JA) 機械学習の精度を向上することを可能にする。判断支援装置は、生体サンプルを撮像することで得られた第1病理画像に対する判断の推定結果を各段でクラス分類が設定可能な多段の学習済みモデルを用いて導出する導出部(100)を備える。
