Block subsampled randomized Hadamard transform for low-rank approximation on distributed architectures

Oleg Balabanov, Matthias Beaupere, Laura Grigori +1

This article introduces a novel structured random matrix composed blockwise from subsampled randomized Hadamard transforms (SRHTs). The block SRHT is expected to outperform well-kn…
