On the duality between contrastive and non-contrastive self-supervised learning

ICLR 2023top-5%

Recent approaches in self-supervised learning of image representations can be categorized into different families of methods and, in particular, can be divided into contrastive and non-contrastive approaches. While differences between the two families have been thoroughly discussed to motivate new a…

RankMe: Assessing the Downstream Performance of Pretrained Self-Supervised Representations by Their Rank

ICML 2023oral

Joint-Embedding Self Supervised Learning (JE-SSL) has seen a rapid development, with the emergence of many method variations but only few principled guidelines that would help practitioners to successfully deploy them. The main reason for that pitfall comes from JE-SSL's core principle of not employ…

Self-supervised learning of Split Invariant Equivariant representations

ICML 2023poster

Recent progress has been made towards learning invariant or equivariant representations with self-supervised learning. While invariant methods are evaluated on large scale datasets, equivariant ones are evaluated in smaller, more controlled, settings. We aim at bridging the gap between the two in or…
