NLSR: Neuron-Level Safety Realignment of Large Language Models Against Harmful Fine-Tuning

AAAI 2025technical

The emergence of fine-tuning-as-a-service has revealed a new vulnerability in large language models (LLMs). A mere handful of malicious data uploaded by users can subtly manipulate the fine-tuning process, leading to a compromised alignment state. Existing methods to counteract fine-tuning attacks t…
