Poison Attacks against Text Datasets with Conditional Adversarially Regularized Autoencoder
share
This paper demonstrates a fatal vulnerability in natural language inference (NLI) and text classification systems. More concretely, we present a 'backdoor poisoning' attack on NLP models. Our poisoning attack utilizes conditional adversarially regularized autoencoder (CARA) to generate poisoned training samples by poison injection in latent space. Just by adding 1 our experiments show that a victim BERT finetuned classifier's predictions can be steered to the poison target class with success rates of >80 hypothesis is injected with the poison signature, demonstrating that NLI and text classification systems face a huge security risk.
