新方法通过区分记忆与图像难度来改进扩散模型隐私审计

研究人员开发了新的方法来提高扩散模型成员推断攻击(MIA)的准确性,该攻击用于检测特定图像是否是模型训练数据的一部分。使用重建损失的标准方法存在缺陷,因为图像难度可能被误认为是记忆。新的技术,参考模型校准(RMC)和时间自校准(TSC),分别通过校准训练和扩散时间的图像难度来解决这个问题。RMC将微调模型的损失与早期检查点进行比较,而TSC利用图像难度随时间保持一致而记忆是局部化的观察结果,使用单个模型跨扩散时间步长比较损失。这些方法在现有最先进的攻击中表现出色,并能推广到不同的扩散模型参数化。 AI

    扩散模型中成员推断的跨时间难度校准

    Modern diffusion models are trained on massive datasets that often include copyrighted or private images. Membership inference attacks (MIAs) address this by testing whether a given image was in a model's training set. The standard approach scores an image by its reconstruction l…
