Abstract

The chapter 'MIC: An Effective Defense Against Word-Level Textual Backdoor Attacks' explores the vulnerabilities of NLP models to backdoor attacks, particularly focusing on word-level attacks. It introduces the MIC defense method, which incorporates metric learning and contrastive learning to prevent backdoor implantation and improve model robustness. The method is evaluated on several datasets, demonstrating superior performance compared to existing defense techniques. The chapter highlights the importance of preemptive defense strategies in model training to mitigate the risks posed by stealthy backdoor attacks.
