Contrastive Learning Via Equivariant Representation

no code implementations1 Jun 2024 Sifan Song, Jinfeng Wang, Qiaochu Zhao, Xiang Li, Dufan Wu, Angelos Stefanidis, Jionglong Su, S. Kevin Zhou, Quanzheng Li

We propose CLeVER (Contrastive Learning Via Equivariant Representation), a novel equivariant contrastive learning framework compatible with augmentation strategies of arbitrary complexity for various mainstream CL backbone models.

Distortion-Disentangled Contrastive Learning

no code implementations9 Mar 2023 Jinfeng Wang, Sifan Song, Jionglong Su, S. Kevin Zhou

The POCL method typically uses a single loss function to extract the distortion invariant representation (DIR) which describes the proximity of positive-pair representations affected by different distortions.
