Adaptive Randomized Tensor Train Rounding using Khatri-Rao Products
Hussam Al Daas, Grey Ballard, Laura Grigori +3
Approximating a tensor in the tensor train (TT) format has many important applications in scientific computing. Rounding a TT tensor involves further compressing a tensor that is a…
Extended-Krylov-subspace methods for trust-region and norm-regularization subproblems
Hussam Al Daas, Nicholas I. M. Gould
We consider an effective new method for solving trust-region and norm-regularization problems that arise as subproblems in many optimization applications. We show that the solution…
Minimal residual rational Krylov subspace method for sequences of shifted linear systems
Hussam Al Daas, Davide Palitta
The solution of sequences of shifted linear systems is a classic problem in numerical linear algebra, and a variety of efficient methods have been proposed over the years. Neverthe…
Minimizing Communication for Parallel Symmetric Tensor Times Same Vector Computation
Hussam Al Daas, Grey Ballard, Laura Grigori +3
In this article, we focus on the parallel communication cost of multiplying the same vector along two modes of a -dimensional symmetric tensor. This is a key computation in the…
