An information processing device (1) provided with: an accuracy degradation cause acquisition means (2) that acquires the cause of accuracy degradation of an analysis model; an improvement measure acquisition means (3) that acquires improvement measures for the analysis model that correspond to the cause of the accuracy degradation of the analysis model; and a display means (4) that displays the improvement measures for the analysis model. The information processing device (1) may be further provided with: a determination means that determines whether or not the analysis model satisfies evaluation criteria; an extraction means that, if it is determined that the analysis model does not satisfy the evaluation criteria, extracts, from data of the analysis model, information necessary to estimate the cause of the accuracy degradation; and an input means that inputs the information necessary to estimate the cause of the accuracy degradation into a degradation cause estimation device. The accuracy degradation cause acquisition means may acquire improvement measures for the analysis model that are output from the degradation cause estimation device and that correspond to the cause of the accuracy degradation of the analysis model.
