Heterogeneous Federated Learning with Scalable Server Mixture-of-Experts

Published in Proceedings of the International Joint Conference on Artificial Intelligence (IJCAI), 2025

Proposed a novel Federated Mixture-of-Experts (Fed-MoE) framework to address the challenges of deploying large models in power-constrained environments. Designed an asymmetric FL mechanism where compact client models are aggregated into a large server-side MoE model, enabling efficient learning from heterogeneous data.
