Zusammenfassung: | To present prediction basis for a model that is easy to understand.SOLUTION: A prediction basis presentation system for a model that predicts an event by inputting input data composed of values of a plurality of explanatory variables, comprises: a prediction basis output unit that calculates the degree of effect indicating the effect of values of the plurality of explanatory variables on a prediction result and generates prediction basis data composed of the degree of effect of the plurality of explanatory variables; a result output unit that outputs display information for displaying the prediction basis data; and a storage unit that stores the history of the input data and the history of the prediction basis data. The result output unit is configured to generate a group from the explanatory variables which can aggregate and is specified by executing a statistical analysis process using the history of the input data and the history of the prediction basis data, to calculate the aggregate degree of effect from the degree of effect of the plurality of explanatory variables included in the group, to convert the prediction basis data into aggregate prediction basis data, and to generate display information based on the aggregate prediction basis data.SELECTED DRAWING: Figure 1
【課題】理解が容易なモデルの予測根拠を提示する。【解決手段】複数の説明変数の値から構成される入力データを入力して、事象の予測を行うモデルの予測根拠提示システムであって、予測結果に対して、複数の説明変数の値の影響を示す影響度を算出し、複数の説明変数の影響度から構成される予測根拠データを生成する予測根拠出力部と、予測根拠データを表示するための表示情報を出力する結果出力部と、入力データの履歴及び予測根拠データの履歴を格納する記憶部と、を備え、結果出力部は、入力データの履歴及び予測根拠データの履歴を用いた統計分析処理を実行することによって特定された集約可能な説明変数からグループを生成し、グループに含まれる複数の説明変数の影響度から集約影響度を算出し、予測根拠データを集約予測根拠データに変換し、集約予測根拠データに基づいて表示情報を生成する。【選択図】 図1 |
