This paper proposes a new differentially private federated learning optimization algorithm called FedNoise. If I understand correctly, FedNoise introduces noise into the optimization procedure in two places: first, each client perturbs the model parameters before performing local update steps, and second, the clipped update is perturbed with Gaussian noise before applying it to the parameters to provide differential privacy. Perturbing the model parameters before the updates are performed acts as a regularizer and helps client updates generalize to other clients, and a main focus of the paper is deriving the scale of noise that should be added to each layer during the perturbation step (but not the noise for DP, which remains the same scale for all layers). Empirically, the authors also demonstrate the FedNoise performs well on CIFAR10, EMNIST, and Fashion MNIST. 把审稿人的总结翻译成中文
可以,下面是这段审稿人总结的中文翻译:
:::writing{variant="document" id="58321" title="审稿人总结中文翻译"} 本文提出了一种新的差分隐私联邦学习优化算法,称为 FedNoise。如果我的理解正确的话,FedNoise 在优化过程中从两个位置引入噪声:首先,每个客户端在执行本地更新步骤之前,会对模型参数进行扰动;其次,为了提供差分隐私保护,在将经过裁剪(clipping)的更新应用到模型参数之前,还会向该更新中加入高斯噪声。
在执行本地更新之前对模型参数进行扰动可以起到正则化的作用,并有助于客户端的更新更好地泛化到其他客户端。本文的一个主要关注点是推导在这一参数扰动步骤中,应当向模型各层加入多大尺度的噪声(但这里并不是指用于差分隐私的噪声;用于差分隐私的噪声在所有层中仍然采用相同的尺度)。
在实验方面,作者还证明了 FedNoise 在 CIFAR-10、EMNIST 和 Fashion-MNIST 数据集上均取得了良好的性能。 :::
这里审稿人的整体语气是中性偏正面的概括,其中 “If I understand correctly” 表明审稿人在复述自己对方法的理解,后续如果你要写 rebuttal,最好重点确认他对“两处加噪”和“layer-wise noise 仅针对参数扰动、而非 DP 噪声”的理解是否准确。
