新技术使用模型曲率改进 DP-SGD 的准确性

研究人员开发了一种名为 NoiseCurve 的新技术,以提高差分隐私随机梯度下降 (DP-SGD) 的准确性。该方法利用从无标签数据估计出的模型曲率,来增强不同训练迭代中隐私噪声的相关性。实验表明,在各种数据集和模型上,NoiseCurve 相比现有的 DP-MF 相关方案提供了持续的准确性改进。 AI

影响 这项研究可能带来更准确的差分隐私模型,从而可能增加其在隐私敏感应用中的采用率。

    使用模型曲率对DP-SGD进行跨迭代噪声关联

    arXiv:2510.05416v3 Announce Type: replace Abstract: Differentially private stochastic gradient descent (DP-SGD) offers the promise of training deep learning models while mitigating many privacy risks. However, there is currently a large accuracy gap between DP-SGD and normal SGD …
