Hi, I am one of the authors of this EMNLP 2019 paper.

​

We create Universal Adversarial Triggers:

Phrases that cause a specific model prediction when concatenated to 𝘢𝘯𝘺 input.

Triggers cause:

– GPT-2 to turn racist

– SQuAD models to predict “to kill american people” for 72% of “why” questions

– Text classifier accuracy 90%->1%.
