### Nonlinear Analysis Seminar and Differential Equation Seminar: Edouard Pauwels, Université de Toulouse, Nonsmooth differentiation of parametric fixed points

ZoomRecent developments in the practice of numerical programming require optimization problems not only to be solved numerically, but also to be differentiated. This allows to integrate the computational operation of evaluating a solution in larger models, which are themselves trained or optimized using gradient methods. Most well known applications include bilevel optimization and implicit input-output…
