Rethinking Sharpness-Aware Minimization as Variational Inference

no code implementations19 Oct 2022 Szilvia Ujváry, Zsigmond Telek, Anna Kerekes, Anna Mészáros, Ferenc Huszár

Sharpness-aware minimization (SAM) aims to improve the generalisation of gradient-based learning by seeking out flat minima.

Variational Inference

Estimating optimal PAC-Bayes bounds with Hamiltonian Monte Carlo

no code implementations30 Oct 2023 Szilvia Ujváry, Gergely Flamich, Vincent Fortuin, José Miguel Hernández Lobato

An important yet underexplored question in the PAC-Bayes literature is how much tightness we lose by restricting the posterior family to factorized Gaussian distributions when optimizing a PAC-Bayes bound.
