New Lower Bounds for the Minimum Singular Value in Matrix Selection

Zhiqiang Xu

The objective of the matrix selection problem is to select a submatrix $A_{S} \in R^{n \times k}$ from $A \in R^{n \times m}$ such that its minimum singular value is…

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…
