Information processing apparatus, method, and program

An information processing method executed by a computer, the method comprising:

• dividing a plurality of pieces of construction data used to construct a learning model into a plurality of data sets having a common probability distribution followed by the construction data;
• applying a hyperparameter selected from a plurality of hyperparameters related to the learning model to the learning model to derive an evaluation result for each of the plurality of data sets;
• determining a lowest evaluation result from among the evaluation results for each of the plurality of data sets as an evaluation value for the selected hyperparameter;
• and
• determining the hyperparameter by repeating the derivation of the evaluation result and the determination of the evaluation value while changing the hyperparameter until an end condition is satisfied.

A non-transitory computer-readable storage medium that stores an information processing program causing a computer to execute:

• a procedure of dividing a plurality of pieces of construction data used to construct a learning model into a plurality of data sets having a common probability distribution followed by the construction data;
• a procedure of applying a hyperparameter selected from a plurality of hyperparameters related to the learning model to the learning model to derive an evaluation result for each of the plurality of data sets;
• a procedure of determining a lowest evaluation result from among the evaluation results for each of the plurality of data sets as an evaluation value for the selected hyperparameter;
• and
• a procedure of determining the hyperparameter by repeating the derivation of the evaluation result and the determination of the evaluation value while changing the hyperparameter until an end condition is satisfied.
