Dynamic Differential-Privacy Preserving SGD

no code implementations30 Oct 2021 Jian Du, Song Li, Xiangyi Chen, Siheng Chen, Mingyi Hong

The equivalent privacy costs controlled by maintaining the same gradient clipping thresholds and noise powers in each step result in unstable updates and a lower model accuracy when compared to the non-DP counterpart.
