Evaluation Framework For Large-scale Federated Learning

1 code implementation3 Mar 2020 Lifeng Liu, Fengda Zhang, Jun Xiao, Chao Wu

Federated learning is proposed as a machine learning setting to enable distributed edge devices, such as mobile phones, to collaboratively learn a shared prediction model while keeping all the training data on device, which can not only take full advantage of data distributed across millions of nodes to train a good model but also protect data privacy.
