CoT-BERT: Enhancing Unsupervised Sentence Representation through Chain-of-Thought
核心概念
CoT-BERT proposes a two-stage approach for sentence representation, leveraging Chain-of-Thought and contrastive learning to enhance unsupervised models like BERT.
摘要
- Unsupervised sentence representation learning aims to transform input sentences into fixed-length vectors enriched with semantic information.
- Recent progress in the field has bridged the gap between unsupervised and supervised strategies.
- CoT-BERT introduces a two-stage approach for sentence representation: comprehension and summarization.
- The method outperforms baselines without external components, showcasing the effectiveness of the proposed techniques.
- CoT-BERT's extended InfoNCE Loss and template denoising strategy contribute to its success.
