Parameter selection method, computer-readable recording medium recording parameter selection program, and information processing device

A non-transitory computer-readable recording medium recording a parameter selection program that causes a computer to perform processing comprising:

• calculating a response surface that predicts an evaluation value, from evaluation values obtained from training data and sets of parameter values, which are stored in a memory;
• working out, from each of maximum evaluation values among the obtained evaluation values, shortest distances to a contour line defined at a position equal to or smaller than the maximum evaluation values on the calculated response surface;
• and
• specifying a set of parameter values farthest from the contour line, from among the shortest distances worked out for each of the maximum evaluation values.

An information processing device comprising:

• a memory;
• and
• a processor coupled to the memory and configured to:
• calculate a response surface that predicts an evaluation value, from evaluation values obtained from training data and sets of parameter values, which are stored in the memory;
• and
• work out, from each of maximum evaluation values among the obtained evaluation values, shortest distances to a contour line defined at a position equal to or smaller than the maximum evaluation values on the calculated response surface, and specifies a set of parameter values farthest from the contour line, from among the shortest distances worked out for each of the maximum evaluation values, from among the worked-out shortest distances.
