Lecture notes on non-convex algorithms for low-rank matrix recovery
Irène Waldspurger
Low-rank matrix recovery problems are inverse problems which naturally arise in various fields like signal processing, imaging and machine learning. They are non-convex and NP-hard…

Rank optimality for the Burer-Monteiro factorization
Irène Waldspurger, Alden Waters
When solving large scale semidefinite programs that admit a low-rank solution, an efficient heuristic is the Burer-Monteiro factorization: instead of optimizing over the full matri…

Exponential decay of scattering coefficients
Irène Waldspurger
We study an aspect of the following general question: which properties of a signal can be characterized by its scattering transform? We show that the energy contained in high order…
