What is it about?
This paper introduces a Bayesian calibration method called "on-site surrogates" for large-scale computer experiments. Through leveraging divide-and-conquer on filed experimental input sites, this on-site approach focuses design and modeling on calibration parameter only. This approach scales up the canonical Bayesian calibration framework into large-scale, high-dimension, and nonstationary settings, maintaining high-fidelity and flexibility at the same time.

Why is it important?
This on-site approach to calibration scales up Bayesian calibration framework for large-scale computer simulation experiments (with big p and n), at the same time naturally addressing several challenges of high-dimensional, non-stationary, and complex response surfaces with high fidelity.
