A Numerical Evaluation of an Infill Sampling Criterion in Artificial Neural Network-Based Optimization

Abstract—Surrogate models can be used to replace expensive computer simulations for the purposes of optimization. In this paper, we propose an optimization approach based on artificial neural network (ANN) surrogate models and infill sampling criteria (ISC) strategy to evaluate design variables. The criterion for infill sample selection is a function which aims at identify design that offer potential improvement. We employ four widely used analytical benchmark problems to test the proposed approach. Our results show that a more accurate surrogate model obtained with fewer points is obtained when one includes the infill sample criterion to an ANN-based optimization.

Index Terms—Surrogate model, design variables, artificial neural network, infill sampling criteria, optimization, benchmark function.
