Summary:To enhance usefulness of an inference result that is output from a learned model by receiving input of a plurality of explanatory variables.SOLUTION: A data processing device according to an aspect comprises: an inference unit that predicts at least one objective variable from a plurality of explanatory variables using a learned model; and a display data generation unit that generates data for displaying a result of inference performed by the inference unit. The inference unit defines a first explanatory variable selected from among the plurality of explanatory variables as a variable value, and defines a second explanatory variable other than the first explanatory variable as a fixed value. The inference unit predicts at least one objective variable at time when the first explanatory variable is continuously varied within a predetermined variation range using the learned model. The display data generation unit generates data indicating variation of the at least one objective variable for variation of the first explanatory variable.SELECTED DRAWING: Figure 11 【課題】複数の説明変数の入力を受けて学習済みモデルから出力される推論結果の有用性を高める。【解決手段】一態様に係るデータ処理装置は、学習済みモデルを用いて、複数の説明変数から少なくとも1つの目的変数を予測する推論部と、推論部による推論結果を表示するためのデータを生成する表示データ生成部とを備える。推論部は、複数の説明変数の中から選択された第1の説明変数を変動値とする一方で、第1の説明変数以外の第2の説明変数を固定値とする。推論部は、学習済みモデルを用いて、第1の説明変数を予め定められた変動範囲内で連続的に変動させたときの少なくとも1つの目的変数を予測する。表示データ生成部は、第1の説明変数の変動に対する少なくとも1つの目的変数の変動を示すデータを生成する。【選択図】図11
