Abstract
(EN)
An information processing device 100 according to the present invention is provided with: a prediction value calculation unit 110 for calculating, on the basis of a model for calculating an objective variable indicating a state of a subject by using a plurality of explanatory variables, for each explanatory variable, prediction values of the explanatory variables, which change on the basis of values of the explanatory variables at a predetermined point of time; and a change amount calculation unit 120 for calculating, by using the prediction values of the explanatory variables and the model, a change amount of the objective variable caused by changes of the explanatory variables for each explanatory variable.
(FR)
L’invention concerne un dispositif de traitement d'informations 100 qui comprend : une unité de calcul de valeur de prédiction 110 destinée à calculer, sur la base d'un modèle pour calculer une variable objective indiquant un état d'un sujet à l'aide d'une pluralité de variables explicatives, pour chaque variable explicative, des valeurs de prédiction des variables explicatives, qui changent sur la base de valeurs des variables explicatives à un instant prédéterminé ; et une unité de calcul de quantité de changement 120 destinée à calculer, à l'aide des valeurs de prédiction des variables explicatives et du modèle, une quantité de changement de la variable objective provoquée par des changements des variables explicatives pour chaque variable explicative.
(JA)
本発明の情報処理装置100は、複数の説明変数を用いて対象の状態を表す目的変数を算出するモデルに基づいて、説明変数ごとに、当該説明変数の所定時点の値に基づいて変化する当該説明変数の予測値を算出する予測値算出部110と、説明変数ごとに、当該説明変数の予測値と前記モデルとを用いて、当該説明変数の変化による目的変数の変化量を算出する変化量算出部120と、を備える。
