Balancing Privacy Protection and Interpretability in Federated Learning

no code implementations16 Feb 2023 Zhe Li, Honglong Chen, Zhichen Ni, Huajie Shao

Federated learning (FL) aims to collaboratively train the global model in a distributed manner by sharing the model parameters from local clients to a central server, thereby potentially protecting users' private information.
