On the complexity of nonsmooth automatic differentiation
Jérôme Bolte, Ryan Boustany, Edouard Pauwels +1
Using the notion of conservative gradient, we provide a simple model to estimate the computational costs of the backward and forward modes of algorithmic differentiation for a wide…
A Proximal Approach for Sparse Multiclass SVM
G. Chierchia, Nelly Pustelnik, Jean-Christophe Pesquet +1
Sparsity-inducing penalties are useful tools to design multiclass support vector machines (SVMs). In this paper, we propose a convex optimization approach for efficiently and exact…
A Non-Local Structure Tensor Based Approach for Multicomponent Image Recovery Problems
Giovanni Chierchia, Nelly Pustelnik, Beatrice Pesquet-Popescu +1
Non-Local Total Variation (NLTV) has emerged as a useful tool in variational methods for image recovery problems. In this paper, we extend the NLTV-based regularization to multicom…
Epigraphical splitting for solving constrained convex formulations of inverse problems with proximal tools
Giovanni Chierchia, Nelly Pustelnik, Jean-Christophe Pesquet +1
We propose a proximal approach to deal with a class of convex variational problems involving nonlinear constraints. A large family of constraints, proven to be effective in the sol…
Consistent Reconstruction of the Input of an Oversampled Filter Bank From Noisy Subbands
Manel Abid, Michel Kieffer, Beatrice Pesquet-Popescu
This paper introduces a reconstruction approach for the input signal of an oversampled filter bank (OFB) when the sub-bands generated at its output are quantized and transmitted ov…
