Group Privacy Amplification and Unified Amplification by Subsampling for Rényi Differential Privacy
The author explores the joint study of group privacy and amplification by subsampling in the context of Rényi-DP, providing a unified framework for deriving guarantees. This approach leads to novel and tight guarantees for various mechanisms.
