New technique improves DP-SGD accuracy using model curvature

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new technique called NoiseCurve to improve the accuracy of differentially private stochastic gradient descent (DP-SGD). This method uses model curvature, estimated from unlabeled data, to enhance the correlation of privacy noise across different training iterations. Experiments demonstrate that NoiseCurve offers consistent accuracy improvements over existing DP-MF correlation schemes across various datasets and models. AI

IMPACT This research could lead to more accurate differentially private models, potentially increasing their adoption in privacy-sensitive applications.

    Correlating Cross-Iteration Noise for DP-SGD using Model Curvature

    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 …
