摘要: The use of kriging models for approximation and global optimization has been steadily on the rise in past decade. standard approach used Design Analysis Computer Experiments (DACE) is to an Ordinary model approximate a deterministic computer model. Universal Detrended are two alternative types models. In this paper, description basics given, highlighting similarities differences between these three different underlying assumptions behind each. A comparative study then presented using six test problems. methods Maximum Likelihood Estimation (MLE) Cross-Validation (CV) parameter estimation compared types. one-dimension problem first visualize order show applications higher dimensions, four two-dimension 5-dimension also given.Copyright © 2003 by ASME
