What happened
Collection of new arXiv submissions (info theory / communications / ML) covering advances in differential privacy, coding and beamforming, sensing and communication trade-offs, and learning/estimation theory. Key security-relevant items: (1) a local (pure) DP mechanism using correlated noise that matches centralized-DP estimation cost (may change local-privacy deployment tradeoffs); (2) a Fast Mixing DP sketching mechanism and a fast DP OLS algorithm (practical DP inference with improved runtime); (3) a distributionally-robust physical-layer secrecy formulation for multi-beam satellite links,́
