Papers with gradient-guided search
Universal Adversarial Triggers for Attacking and Analyzing NLP (D19-1)
Copied to clipboard
| Challenge: | Using adversarial triggers, a model can produce a specific prediction . adversarial attacks are useful for evaluation and interpretation . |
| Approach: | They propose a gradient-guided search over tokens that finds short adversarial triggers that successfully trigger the target prediction. |
| Outcome: | The proposed algorithm finds short trigger sequences that successfully trigger the target prediction. |
AutoPrompt: Eliciting Knowledge from Language Models with Automatically Generated Prompts (2020.emnlp-main)
Copied to clipboard
| Challenge: | Pretrained language models have been successful when finetuned to downstream tasks . however, it is difficult to determine whether the knowledge that finetuning LMs contain is learned during the pretraining or the finetailing process. |
| Approach: | They propose a method to create prompts for a diverse set of tasks using a gradient-guided search. |
| Outcome: | The proposed method performs sentiment analysis and natural language inference without additional parameters and finetuning. |
