English(EN) Addressing Over-Refusal in LLMs with Competing Rewards

新的LLM安全训练方法鼓励有害推理以获得更好的安全性

研究人员开发了一种新颖的方法来缓解大型语言模型(LLM)中的过度拒绝问题,通过重新构建安全训练。新方法不是仅仅阻止有害推理,而是鼓励模型探索潜在不安全的想法,以此来更好地区分有害和无害的提示。这种对抗性优化技术训练一个单一模型,使其既扮演探索不安全策略的推理角色,又扮演确保安全最终输出的回答角色。由此产生的模型SEAR在提高安全性的同时,减少了对良性查询的不必要拒绝,并增强了对推理操纵攻击的防御能力。 AI

影响 这种方法可以通过减少对良性提示的过度拒绝,从而使LLM更安全、更有用。

    解决大型语言模型中的过度拒绝问题:通过竞争性奖励

    Safety training on language models often induces over-refusal: improved safety on harmful prompts at the cost of increased refusal on harmless ones. Though this trade-off can be mitigated by training models with reinforcement learning (RL) to reason before answering, it does not …
