Researchers have developed a new framework for differentially private (DP) optimization in federated learning settings. This method, called DP-PCA, aims to reduce communication costs while maintaining central DP guarantees. It achieves this through a DP rank selection step, a DP power method, and a noisy release of a projected covariance matrix, enabling preconditioned DP gradient descent with significantly lower communication than existing centralized methods.
