This study compared hyperparameter updating strategies for maximum entropy sequential design in computer experiments, finding ML-II and MAP+FullBayes offer comparable accuracy but differ in uncertainty quantification, while INLA proves computationally expensive.

Abstract

Abstract This paper investigates maximum entropy sequential design for deterministic computer experiments using Gaussian process surrogates under a fixed simulation budget. We systematically compare three hyperparameter updating strategies: (i) Type-II maximum likelihood (ML-II/empirical Bayes) via marginal likelihood maximization, (ii) INLA-based approximate Bayesian updating, and (iii) maximum a posteriori (MAP) with full Bayesian propagation using MCMC. Performance is evaluated using pointwise RMSE, posterior predictive RMSE, integrated posterior variance, an entropy proxy, and computational cost. On the Forrester and Branin benchmarks, ML-II and MAP+FullBayes achieve comparable pointwise accuracy, but ML-II contracts uncertainty more aggressively, while MAP+FullBayes retains larger uncertainty due to hyperparameter propagation. INLA maintains higher integrated variance and incurs substantially greater computational cost under the present configuration. Our findings demonstrate that entropy-based sampling reliably identifies informative regions, while the updating mechanism governs the trade-off between computational efficiency and uncertainty quantification.
