US 2018/0285317 A1 · MODEL GENERATION SYSTEM AND MODEL GENERATION METHOD

Abstract

According to one embodiment, a model generation system includes a base model generator, a similarity calculator, a modified model generator, and a generalization ability calculator. The base model generator generates a base model of a relationship between an input variable group and an output variable. The input variable group includes selected input variables selected from input variables. The similarity calculator calculates each similarity between the selected input variables and unselected input variables. The unselected input variables is included in the input variables. The modified model generator interchanges at least a portion of the plurality of selected input variables with at least a portion of the plurality of unselected input variables to generate another input variable group. The modified model generator generates a modified model of a relationship between the output variable and the other input variable group. The generalization ability calculator calculates generalization abilities of the models.
