Fast randomized algorithms for low-rank matrix approximations with applications in global comparative analysis of a class of data sets
Weiwei Xu, Weijie Shen, Wen Li +2
Generalized singular values (GSVs) play an essential role in the comparative analysis. In the real world data for comparative analysis, both data matrices are usually numerically l…
