Perspectives on CUR Decompositions
Keaton Hamm, Longxiu Huang · arXiv (Cornell University) · 2019
This note discusses an interesting matrix factorization called the CUR Decomposition. We illustrate various viewpoints of this method by comparing and contrasting them in different situations. Additionally, we offer a new characterization of CUR decompositions which synergizes these viewpoints and shows that they are indeed the same in the exact decomposition case.
