Document Type and Number:

Japanese Patent JP7375990

Kind Code:

B2

Abstract:

This information processing device 1 outputs the predicted value of a result variable that corresponds to an inputted explanatory variable, using a prediction model having been constructed by training a prediction object with the relationship of the explanatory and result variables. The information processing device 1 comprises: an acquisition unit 31 for acquiring the explanatory variable inputted to the prediction model and the predicted value outputted from the prediction model; an error calculation unit 32 for calculating an error between the actual and predicted values of the result variable that corresponds to the explanatory variable; a candidate explanatory variable acquisition unit 33 for acquiring a candidate explanatory variable that is the candidate for the explanatory variable causing the error; a similar prediction object acquisition unit 34 for acquiring an object, as a similar prediction object, that is similar to the prediction object and which is free of errors caused by the candidate explanatory variable; and an evaluation unit 36 for calculating an influence value of the candidate explanatory variable so as to be progressively higher as the difference between the actual value of the result variable corresponding to the candidate explanatory variable in the prediction object and the actual value of the result variable corresponding to the candidate explanatory variable in the similar prediction object increases.
