新的 RACER 框架修复多模态大语言模型中的后门

研究人员开发了 RACER,一个旨在修复多模态大语言模型 (MLLMs) 中后门的新型框架。与之前专注于推理时过滤的方法不同,RACER 在模型层面运行以消除潜在的后门。它识别并解决模型内部表示中依赖于模态的异常,特别针对编码触发特征的区域。通过对抗性微调,RACER 在保留模型在干净任务上的效用的同时,有效抑制了后门行为。 AI

影响 通过消除潜在的后门漏洞,引入了一种增强已部署 MLLMs 安全性和可靠性的新方法。

    并非所有 Token 都相等:多模态大语言模型后门中的区域感知一致性修复

    arXiv:2608.24354v1 Announce Type: cross Abstract: MLLMs are increasingly deployed in user-facing applications, yet they inherit backdoor risks from the pipelines used to construct them: triggers may reside in images, texts, or both. Existing model-level backdoor removal methods, …
