DP-MacAdam: Differentially Private Mechanism with Adaptive Clipping and Adaptive Momentum

In three linesDP-MacAdam combines adaptive clipping and adaptive momentum in DP-SGD. The algorithm reuses the same mean and variance estimates to adjust the clipping threshold and accelerate training. Empirical evaluation shows improved model utility vs DP-SGD, AdaClip, DP-Adam without manual threshold tuning.
