Interlacing Polynomial Method for Matrix Approximation via Generalized Column and Row Selection

Jian-Feng Cai, Zhiqiang Xu, Zili Xu

This paper delves into the spectral norm aspect of the Generalized Column and Row Subset Selection (GCRSS) problem. Given a target matrix $A \in R^{n \times d}$ , th…

Interlacing Polynomial Method for the Column Subset Selection Problem

Jian-Feng Cai, Zhiqiang Xu, Zili Xu

This paper investigates the spectral norm version of the column subset selection problem. Given a matrix $A \in R^{n \times d}$ and a positive integer $k\leq\text{ra…
