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.
統計
Unsupervised sentence representation learning aims to transform input sentences into fixed-length vectors enriched with intricate semantic information.
Recent progress within this field, propelled by contrastive learning and prompt engineering, has significantly bridged the gap between unsupervised and supervised strategies.
CoT-BERT proposes a two-stage approach for sentence representation: comprehension and summarization.
The method outperforms several robust baselines without necessitating additional parameters.
CoT-BERT introduces a superior contrastive learning loss function that extends beyond the conventional InfoNCE Loss.
