Gradient-based Adversarial Attacks against Text Transformers (2021.emnlp-main)
Copied to clipboard
| Challenge: | Existing methods for obtaining adversarial examples are difficult with text data. |
| Approach: | They propose a gradient-based adversarial attack against transformer models that searches for a distribution of adversarials parameterized by a continuous-valued matrix. |
| Outcome: | The proposed attack outperforms existing methods on a variety of natural language tasks with matching imperceptibility. |
