This repository contains various analysis in the realm of mode connectivity. It is based on the PyTorch implementation of the curve-finding and Fast Geometric Ensembling (FGE) procedures from the paper Loss Surfaces, Mode Connectivity, and Fast Ensembling of DNNs by Timur Garipov, Pavel Izmailov, Dmitrii Podoprikhin, Dmitry Vetrov and Andrew Gordon Wilson (NIPS 2018, Spotlight).
