Modeling Adversarial Attack on Pre-trained Language Models as Sequential Decision Making (2023.findings-acl)
Copied to clipboard
| Challenge: | Pre-trained language models (PLMs) have shown strong potential in various downstream tasks. |
| Approach: | They propose to model adversarial attack task as a sequential decision-making problem where the whole attack process is sequential with two decision- making problems, i.e., word finder and word substitution. |
| Outcome: | The proposed approach achieves the highest attack success rate with a comparable modification rate and semantic similarity to attack fine-tuned BERT. |
