INFORMATION PROCESS DEVICE, DATA DECOMPOSITION METHOD, AND STORAGE MEDIUM STORING DATA DECOMPOSITION PROGRAM

摘要

By an information process device, a data decomposition method, or a data decomposition program stored in a computer-readable non-transitory storage medium, model data including multiple values is approximated by approximate data including a combination of basis data and coefficient data. A basis data candidate that constitutes the approximate data is selected. An approximate data candidate and an evaluation metric that evaluates the approximate data candidate are calculated. A regression model representing a relationship between the evaluation metric and the basis data candidate is generated. The selection, calculation, and generation are executed at least once. The coefficient data is calculated. The basis data candidate is selected to cause the regression model to more accurately predict the evaluation metric.
