Scalable Hierarchical Over-the-Air Federated Learning
Scalable Hierarchical Over-the-Air Federated Learning
When implementing hierarchical federated learning over wireless networks, scalability assurance and the ability to handle both interference and device data heterogeneity are crucial. This work introduces a new two-level learning method designed to address these challenges, along with a scalable over-the-air aggregation scheme for the uplink and a bandwidth-limited broadcast …
