METHOD FOR DESCRIBING PREDICTION MODEL, NON-TRANSITORY COMPUTER-READABLE STORAGE MEDIUM FOR STORING PREDICTION MODEL DESCRIPTION PROGRAM, AND PREDICTION MODEL DESCRIPTION DEVICE

摘要

A method includes: selecting a plurality of models by using data set and a prediction result of a prediction model for the data set, each model being configured to linearly separate data included in the data set input to the prediction model; creating a decision tree such that a leaf of the decision tree corresponds to each selected model and a node of the decision tree corresponds to each of logics classifying the data from a root to each leaf of the decision tree; specifying a branch to be pruned by using variation in the data belonging to each leaf of the created decision tree; recreating the decision tree by using the data set corresponding to the decision tree in which the specified branch has been pruned; and outputting each of the logics corresponding to each node of the recreated decision tree as a description result of the prediction model.
