About this collection Collection in progress We are building a large AI safety paper collection to help researchers find work related to their interests. Papers are collected automatically andfiltered only for relevance to AI safety , without judging quality, novelty or reading value. The default “Annotated first” shows papers with tags or published paper analyses first. Each group is ordered by original publication date, newest first, with undated papers last. “Newest first” uses publication dates only. This order is not a quality ranking.
One-line summaries, tags and paper analyses are prepared by AI from the papers. Language models may have systematic biases and produce hallucinations.We plan to carry out human annotation and review to reduce errors in this content.
证明预训练投毒的清洁超额风险指数随极限顺序变化
Published Sep 26
Evaluated models OLMo-style models Abstract 投毒清洁超额风险的幂指数取决于先固定宽高比还是先取充足数据极限。可解的预训练数据投毒理论:清洁超额风险的缩放指数随极限顺序改变。 。
提出 Fed-ADR,用编排服务器协同操纵梯度攻破联邦学习并检测恢复
Published Sep 23
Evaluated models CNN(MNIST:2 Conv + 3 FC) , CNN(Fashion-MNIST:6 Conv + 1 FC) , ResNet18(CIFAR-10) Abstract Fed-ADR 用 gray-box 编排攻击绕过多种聚合防御,再用 Hessian 一致性检测和窗口内恢复把准确率拉回。Fed-ADR 是一套面向联邦学习的攻击、检测与恢复框架:编排服务器改写合谋客户端的梯度,使参数服务器的现有防御把投毒更新当成良性,同时在发现后用历史梯度把全局模型原地修回来。
用 Dmax 与尾部损失评测后门修复的类别性能保持

Evaluated models ResNet18 , PreActResNet18 , VGG19-BN 提出 UBA-ORL,以 BD/CM 样本在遗忘后激活离线 RL 后门
Published Sep 19
Evaluated models TD3+BC , BCQ , IQL Abstract UBA-ORL 用竞争的 BD/CM 样本,使离线 RL 后门在删除伪装轨迹后激活。UBA-ORL 研究离线强化学习中由合规轨迹删除激活的后门:合法贡献者同时上传共享触发的后门轨迹和伪装轨迹,训练后触发响应被压低,删除伪装批次后再升高。受害系统是使用静态数据集和轨迹级遗忘接口的离线 RL 服务。对手不能看到训练算法、参数、梯度或具体遗忘算法,但能提交可区分批次,并在部署时向观测注入预定触发。
提出 BPI 选点算法,增强去中心化联邦学习中的模型与数据投毒
Published Sep 2 Abstract BPI 用有限轮 gossip 暴露选拜占庭集合。作者把 DFL 中“破坏哪 m 个节点”写成攻击者在固定预算下的优化问题,并用 BPI 近似有限轮内诚实节点受到的拜占庭暴露。
构造可通过计费审计的 token 虚报,使服务商系统性超收
Published May 28
Evaluated models PALACE domain-adapted auditor Abstract 不诚实提供方可在三种 token 审计上虚报并通过检查,作者认为需改用提供方不控制的证据。不透明 LLM 的按 token 计费里,现有审计核验的是提供方可控的证据,不诚实提供方可以虚报并通过检查。 。
提出 Disclaimer Injection,利用对齐机制使文本难以被学习
Published Jan 7
Evaluated models LLaMA-3-8B-Instruct Abstract 黑盒声明注入压低微调分数,作者把它归因于对齐层持续激活。作者提出数据级方法 Disclaimer Injection ,在 black-box 条件下降低文本被当代 LLM 微调学会的程度。所有者公开文本时未必打算供人训练。作者认为抓取之后法律手段难起作用,而早期模型上的表层扰动要么被当代 LLM 恢复语义,要么损坏可读性。
