A Continuous Exact $\ell_0$ Penalty (CEL0) for Least Squares Regularized Problem
TL;DR: This paper proposes the continuous exact $ell_0$ penalty (CEL0) leading to a tight continuous relaxation of the $\ell_2-\ell-0$ problem, and demonstrates that from each local minimizer of the CEL0 functional, a local minimizers of $\ell-2 - \ell- 0$ is easy to obtain.
Journal ArticleDOI
The Sliding Frank-Wolfe Algorithm and its Application to Super-Resolution Microscopy
TL;DR: In this article, the Sliding Frank-Wolfe (SFC) algorithm is used to solve the SLASSO sparse spikes super-resolution problem, which is a continuous version of the 1-SASSO regularization method.
Proceedings ArticleDOI
High density molecule localization for super-resolution microscopy using CEL0 based sparse approximation
TL;DR: This work forms the localization problem as a sparse approximation problem which is then relaxed using the recently proposed CEL0 penalty, allowing an optimization through recent nonsmooth nonconvex algorithms.
Journal ArticleDOI
A Unified View of Exact Continuous Penalties for $\ell_2$-$\ell_0$ Minimization
TL;DR: Questions are answered by deriving necessary and sufficient conditions on such $\ell_0$ continuous approximations in order that each (local and global) minimizers of the underlying relaxation is also a minimizer of the $\ell-2$-$\ell-0$ functional and that all the global minimization of the initial functional are preserved.
