Towards Better Understanding of Contrastive Sentence Representation Learning: A Unified Paradigm for Gradient

no code implementations28 Feb 2024 Mingxin Li, Richong Zhang, Zhijie Nie

To address these questions, we start from the perspective of gradients and discover that four effective contrastive losses can be integrated into a unified paradigm, which depends on three components: the Gradient Dissipation, the Weight, and the Ratio.
