Data-Driven Performance Guarantees for Classical and Learned Optimizers

no code implementations22 Apr 2024 Rajiv Sambharya, Bartolomeo Stellato

We build generalization guarantees for classical optimizers, using a sample convergence bound, and for learned optimizers, using the Probably Approximately Correct (PAC)-Bayes framework.

Lifted Neural Networks

no code implementations3 May 2018 Armin Askari, Geoffrey Negiar, Rajiv Sambharya, Laurent El Ghaoui

We describe a novel family of models of multi- layer feedforward neural networks in which the activation functions are encoded via penalties in the training problem.
