Efficient iterative methods for hyperparameter estimation in large-scale linear inverse problems
Khalil A Hall-Hooper, Arvind K Saibaba, Julianne Chung +1
We study Bayesian methods for large-scale linear inverse problems, focusing on the challenging task of hyperparameter estimation. Typical hierarchical Bayesian formulations that fo…
Randomized low-rank approximations beyond Gaussian random matrices
Arvind K. Saibaba, Agnieszka Międlar
This paper expands the analysis of randomized low-rank approximation beyond the Gaussian distribution to four classes of random matrices: (1) independent sub-Gaussian entries, (2)…
Randomized Reduced Basis Methods for Parameterized Fractional Elliptic PDEs
Harbir Antil, Arvind K. Saibaba
This paper is interested in developing reduced order models (ROMs) for repeated simulation of fractional elliptic partial differential equations (PDEs) for multiple values of the p…
