Recovery of Low-Rank Matrices under Affine Constraints via a Smoothed Rank Function
Mohammadreza Malek-Mohammadi, Massoud Babaie-Zadeh, Arash Amini +1
In this paper, the problem of matrix rank minimization under affine constraints is addressed. The state-of-the-art algorithms can recover matrices with a rank much less than what i…
