Adaptive Randomized Tensor Train Rounding Using Khatri–Rao Products

Abstract. 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 already in the TT format. This paper proposes new randomized algorithms for TT-rounding that use sketches based on Khatri-Rao prod...

Minimal Residual Rational Krylov Subspace Method for Sequences of Shifted Linear Systems

Abstract. 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. Nevertheless, there exist challenging scenarios for which there is still a lack of performant solvers. For instance, state-of-the-art pro...
