Collaborative federated learning protocols must balance privacy guarantees and model accuracy to be mutually beneficial for all participants.
Sammanfattning
The article explores the trade-off between privacy and accuracy in federated learning. It discusses necessary conditions for mutually beneficial protocols and optimal strategies for maximizing total client utility or end-model accuracy. The study covers mean estimation and convex stochastic optimization tasks, considering differential privacy and local data reconstruction loss. The framework includes federated learning protocols, client evaluations, utility functions, and server objectives. The analysis reveals insights into the impact of noise levels, privacy concerns, and accuracy preferences on collaborative learning effectiveness.
