federated learning involves training statistical models over remote devices
or siloed data centers, such as mobile phones or hospitals, while keeping data
localized. Training in heterogeneous and potentially massive networks
introduces novel challenges that require a fundamental depart
通过使用一种叫作 Fog learning 的新学习范式，从边缘设备到云服务器中智能地分布机器学习模型的训练，来增强联邦学习的三个重要维度：网络、异构性和邻近性，并考虑由各种接近程度异构设备组成的多层混合学习框架，通过设备到设备（D2D）通信进行协作学习，使其从联邦学习中用于参数传输的星型网络拓扑迁移到更分布式的规模。
