The Douglas-Rachford Algorithm for Weakly Convex Penalties
İlker Bayram, Ivan W. Selesnick
The Douglas-Rachford algorithm is widely used in sparse signal processing for minimizing a sum of two convex functions. In this paper, we consider the case where one of the functio…

Enhanced Sparsity by Non-Separable Regularization
Ivan W. Selesnick, Iker Bayram
This paper develops a convex approach for sparse one-dimensional deconvolution that improves upon L1-norm regularization, the standard convex approach. We propose a sparsity-induci…

Convex Fused Lasso Denoising with Non-Convex Regularization and its use for Pulse Detection
Ankit Parekh, Ivan W. Selesnick
We propose a convex formulation of the fused lasso signal approximation problem consisting of non-convex penalty functions. The fused lasso signal model aims to estimate a sparse p…
