“…The accuracy of a surrogate model is affected by the type of surrogate model and the quality and quantity of the data set from which it is constructed [19]. Before we use the built surrogate models, the models need to be validated.…”

“…The meta-modeling process involves model fitting or function approximation to the sampled data of design variables and responses from the detailed model (Ryberg, Bäckryd, & Nilsson, 2012). To demonstrate the idea of our proposed framework, one parametric technique (PR), and five non-parametric techniques (Kriging, SVR, RBF, MARS and ANN) are chosen due to their extensive use in metamodeling.…”
