Low-rank matrix estimation is a canonical problem that finds numerous applications in signal processing, machine learning and imaging science.
In this work, we study the general problem of optimizing a convex function F(L) F ( L ) over the set of p×p p × p matrices, subject to rank constraints on L L .
