Carpet: Neural Net based solver for the 1d-TV problem

An adaptive optimization package for the 1d-TV problem for research purpose, proposed in the following paper:

Hamza Cherkaoui, Jeremias Sulam and Thomas Moreau "Learning to solve TV regularised problems with unrolled algorithms", accepted at NeurIPS 2020.

This package implements:

• Classical solver for TV-regularized optimization problems: (primal-dual) ISTA, (primal-dual) FISTA, Condat-Vu.
• Learnable algorithms: All the iterative versions cited above.
