The Relative Gaussian Mechanism and its Application to Private Gradient Descent

no code implementations29 Aug 2023 Hadrien Hendrikx, Paul Mangold, Aurélien Bellet

Leveraging this assumption, we introduce the Relative Gaussian Mechanism (RGM), in which the variance of the noise depends on the norm of the output.
