English(EN) Reinforcement Learning on Benign Facts Amplifies Leakage of Memorized Private Data

强化学习加剧了大型语言模型记忆私人数据的泄露

一项新的研究论文揭示,当强化学习技术应用于良性事实数据时,会无意中增加大型语言模型中已记忆的私人信息的泄露。研究发现,即使训练数据不包含个人身份信息(PII),使用强化学习进行可验证奖励(RLVR)训练的模型,其已记忆的个人身份信息的提取量也显著增加。这种效应在更大的模型上更为明显,其中一个模型中电子邮件地址的逐字回忆增加了 2.4 倍,而推理能力则保持不变。 AI

影响 这项研究突显了大型语言模型训练中潜在的隐私风险,表明即使是良性的微调也可能暴露敏感的记忆数据。

    基于良性事实的强化学习会加剧记忆化私有数据的泄露

    arXiv:2608.21727v1 Announce Type: cross Abstract: Reinforcement learning with verifiable rewards (RLVR) is deployed to make models better at reasoning tasks, but its side effect on what models will divulge is under studied. Here we show that RLVR on facts increases extraction of …
