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…

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…
