Globally supported surrogate model based on support vector regression for nonlinear structural engineering applications

Abstract: This work presents a global surrogate modelling of mechanical systems with elasto-plastic material behaviour based on support vector regression (SVR). In general, the main challenge in surrogate modelling is to construct an approximation model with the ability to capture the non-smooth behaviour of the system under interest. This paper investigates the ability of the SVR to deal with discontinuous and high non-smooth outputs. Two different kernel functions, namely the Gaussian and Matèrn 5/2 kernel functions, … Show more

“…Then, we used the DPR surrogate model to approximate the functional relationships between the three response measures and the four uncertain parameters for each case. In addition to the GPR model, the study developed SVM [ 39 ], ANN [ 40 ], and third-degree polynomial regression models for comparison. Table 5 summarizes the model verification of all four surrogate models for all cases, which were tested using RMSE values on test sample data.…”
