Model optimization device, model optimization method, and program

A model optimization method for optimizing a prediction model configured to generate predicted values of a target variable for an explanatory variable, the model optimization method comprising:

• generating expanded MR data by transforming training data;
• and
• causing the prediction model to learn and optimizing the prediction model based on a first predicted value generated by the prediction model based on the training data, and a second predicted value generated by the prediction model based on the MR data.

A non-transitory computer readable recording medium storing a program for causing a computer to optimize a prediction model configured to generate predicted values of a target variable for an explanatory variable, the program causing the computer to execute:

• generating expanded MR data by transforming training data;
• and
• causing the prediction model to learn and optimizing the prediction model based on a first predicted value generated by the prediction model based on the training data, and a second predicted value generated by the prediction model based on the MR data.
