Implicit differentiation for fast hyperparameter selection in non-smooth convex learning

Quentin Bertrand, Quentin Klopfenstein, Mathurin Massias +4

Finding the optimal hyperparameters of a model can be cast as a bilevel optimization problem, typically solved using zero-order techniques. In this work we study first-order method…
