Abstract
Gaussian process and Gaussian distribution are popular tools for modeling and enjoy a wide range of applications across complex scientific and engineering systems. In this defense, we investigate how the Gaussian process is integrated with the multi-fidelity framework and how matrix-variate Gaussian distribution is utilized to avail matrix completion problems. The defense is composed of the contributions made in these two directions, including (i) a new experimental design approach to multi-fidelity finite element simulations, (ii) a new conglomerate multi-fidelity emulator model utilizing the Gaussian process that enables us to tackle multi-dimensional fidelity parameters, (iii) a new Bayesian matrix completion model utilizing matrix-variate Gaussian process that facilitates subspace estimation and uncertainty quantification, and (iv) a new information recovery framework for piezoresponse microscopy data in material science studies via low-rank matrix completion and uncertainty quantification. We review the current works and demonstrate the new contributions using real-world applications.
