Classification: CPC F  G | IPC F  G

Claim 4:
5. The design method of claim 1, wherein the e1) includes:
i) dividing the input value into K separated subsets;
ii) selecting test folds that do not overlap with each other from the K separated subsets;
iii) training the surrogate model by performing machine learning only with a training fold, which is a portion excluding a test fold from each of the subsets;
iv) deriving a relative error by comparing a predicted value of the surrogate model trained with the training fold with an actual value of the test fold for each of the subsets;
v) summing relative errors derived from the K subsets to derive a relative error sum; and
vi) repeatedly performing the dividing to the deriving of the relative error sum so that a variable value at which the relative error sum is a minimum is derived.
