An Improved Approach for Estimating the Hyperparameters of the Kriging Model for High-Dimensional Problems through the Partial Least Squares Method
Table 1
Results for experiment data (24 input variables, output variables ) obtained by using 99 training points, 52 validation points, and the error given by (18). “Kriging” refers to the ordinary kriging Optimus solution and “KPLS” and “KPLS+K” refer to KPLS and KPLS+K with principal components, respectively. Best results of the relative error are highlighted in bold type.
