Abstract:

The lecture is about the ongoing recent work on differentially private machine learning (DP-ML). Firstly, I will present simple yet effective strategies to improve the performance of DP-stochastic gradient descent (DP-SGD), the widely adopted method for DP-ML. Then I will discuss ways to defend against Byzantine attacks when DP-SGD is used in federated learning. Finally, I will talk about our recent exploration in input perturbation with DP and synthetic data generation, which is another popular approach to DP-ML.
