Abstract
The transition from multi-rounds federated learning to one-shot federated learning (OFL) markedly alleviates communication burden and represents a major step toward realistic deployment. Most existing OFL approaches require clients to perform local training, imposing a substantial computational burden on client side, while others rely on pre-trained models. In this paper, we propose a novel one-shot federated learning framework based on random feature extractor (FedRFE). Unlike existing approaches, it does not require any local model training or pre-trained model, featuring superior resource efficiency. Through comprehensive experiments, we show FedRFE achieves competitive performance while being robust in challenging scenarios including data heterogeneity and client scalability.
