Representation Projection Invariance Mitigates Representation Collapse (2023.findings-emnlp)
Copied to clipboard
| Challenge: | Fine-tuning contextualized representations by pre-trained models can lead to representation degradation, which can result in instability, sub-optimal performance, and weak generalization. |
| Approach: | They propose a regularization method to maintain the information content of representations and reduce representation collapse during fine-tuning. |
| Outcome: | The proposed method outperforms baselines on most tasks and improves out-of-distribution performance. |
