WERank: Towards Rank Degradation Prevention for Self-Supervised Learning Using Weight Regularization

no code implementations14 Feb 2024 Ali Saheb Pasand, Reza Moravej, Mahdi Biparva, Ali Ghodsi

A common phenomena confining the representation quality in Self-Supervised Learning (SSL) is dimensional collapse (also known as rank degeneration), where the learned representations are mapped to a low dimensional subspace of the representation space.
