Achieving Near-optimal Utility for Privacy-Preserving Federated Learning


Core Concepts
The authors aim to achieve near-optimal utility in privacy-preserving federated learning through data generation and parameter distortion.
Abstract
The content discusses the protection mechanisms, trade-offs between privacy and utility, and algorithms for achieving near-optimal utility in privacy-preserving federated learning. It emphasizes the importance of balancing privacy requirements with maintaining high model utility. Federated learning enables collaborative model building without sharing private data. Protection mechanisms distort model parameters to ensure privacy while maintaining utility. The content explores upper bounds for utility loss and trade-offs between privacy leakage and utility. Algorithms are proposed to achieve near-optimal utility while meeting privacy requirements.
Stats
The variance of the added noise is related to the sampling probability. The total variation distance serves as an upper bound for privacy leakage.
