INFORMATION PROCESSING APPARATUS, INFORMATION PROCESSING METHOD, AND COMPUTER PROGRAM PRODUCT

Abstract

An information processing apparatus includes processors. The processors construct a predictive model serving to receive respective pieces of first time-series data of input variables in a first period of time and predicts output variables to be obtained at a time point after the first period of time. The processors calculate third time-series data being time-series data of an index representing an error or a goodness of fit between (i) pieces of second time-series data representing the output variables predicted by the predictive model at time points included in the first period of time and (ii) correct time-series data representing correct answers to the output variables at the time points in the first period of time. The processors construct a time-series causal graph representing causality between the input variables and the index by using the pieces of first time-series data and the third time-series data.
