CLINE: Contrastive Learning with Semantic Negative Examples for Natural Language Understanding (2021.acl-long)
Copied to clipboard
| Challenge: | Pre-trained language models are vulnerable to simple perturbations, causing poor robustness . recent studies show that adversarial training is useless or harmful for the model to detect these semantic changes. |
| Approach: | They propose to use adversarial training to improve the robustness of pre-trained models . they propose to construct negative examples with similar and opposite semantics . |
| Outcome: | Empirical results show that the proposed approach improves on sentiment analysis, reasoning, and reading comprehension tasks. |
