Randomized dual singular value decomposition
Mengyu Wang, Jingchun Zhou, Hanyu Li
We first propose a concise singular value decomposition of dual matrices. Then, the randomized version of the decomposition is presented. It can significantly reduce the computatio…

Block-Randomized Stochastic Methods for Tensor Ring Decomposition
Yajie Yu, Hanyu Li, Jingchun Zhou
Tensor ring (TR) decomposition is a simple but effective tensor network for analyzing and interpreting latent patterns of tensors. In this work, we propose a doubly randomized opti…
