Hierarchical Federated Learning framework redefines networked AI design

This paper proposes Hierarchical Federated Learning (HFL) as an architecture-aware design framework for networked AI, moving beyond its common framing as a communication-saving protocol. The authors argue that HFL should be organized around three axes: architectural parameters, layer-wise optimization decomposition, and layer-wise communication realization. They demonstrate that convergence in HFL is architecture-dependent, shaped by the chosen hierarchy, optimization roles, and communication mechanisms. AI
