A first-order primal-dual algorithm with linesearch
Yura Malitsky, Thomas Pock
The paper proposes a linesearch for a primal-dual method. Each iteration of the linesearch requires to update only the dual (or primal) variable. For many problems, in particular f…

Techniques for Gradient Based Bilevel Optimization with Nonsmooth Lower Level Problems
Peter Ochs, René Ranftl, Thomas Brox +1
We propose techniques for approximating bilevel optimization problems with non-smooth lower level problems that can have a non-unique solution. To this end, we substitute the expre…
