Mitigating backdoor attacks in LSTM-based Text Classification Systems by Backdoor Keyword Identification

no code implementations11 Jul 2020 Chuanshuai Chen, Jiazhu Dai

In this paper, through analyzing the changes in inner LSTM neurons, we proposed a defense method called Backdoor Keyword Identification (BKI) to mitigate backdoor attacks which the adversary performs against LSTM-based text classification by data poisoning.
