Efficient Computation of the Non-convex Quasi-norm Ball Projection with Iterative Reweighted Approach

Qi An, Jiao Wang, Zequn Niu +1

In this study, we focus on computing the projection onto the ${\ell }_p$ quasi-norm ball, which is challenging due to the non-convex and non-Lipschitz nature inherent in the ${\ell }_p$…
