A tensor-based dynamic mode decomposition based on the -product
Arvind K. Saibaba, Misha E. Kilmer, Khalil Hall-Hooper +2
Dynamic mode decomposition (DMD) is a data-driven method for estimating the dynamics of a discrete dynamical system. This paper proposes a tensor-based approach to DMD for applicat…

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…
