BAYESIAN SEQUENTIAL EXPERIMENTAL DESIGN FOR STOCHASTIC KRIGING WITH JACKKNIFE ERROR ESTIMATES

We propose a fully sequential experimental design procedure for stochastic kriging (SK) methodology of fitting unknown response surfaces from simulation experiments. The procedure first estimates the current SK model performance by jackknifing the existing data points. Then, an additional SK model is fitted on the jackknife error estimates to capture the landscape of the current SK model performance. Methodologies for balancing exploration and exploitation trade-off in Bayesian optimization are employed to select the next simulation point. Compared to experimental design procedures, our method is robust to the SK model specifications. We design a dynamic allocation algorithm, which we call kriging-based dynamic stochastic kriging (KDSK), and illustrate its performance through two numerical experiments.
