The Gaussian-Head OFL Family: One-Shot Federated Learning from Client Global Statistics

arXiv:2602.01186v2 Announce Type: replace Abstract: Classical Federated Learning relies on a multi-round iterative process of model exchange and aggregation between server and clients, with high communication costs and privacy risks from repeated model transmissions. In contrast, one-shot federated learning (OFL) alleviates these limitations by reducing communication to a single round, thereby lowering overhead and enhancing practical deployability. Nevertheless, most existing one-shot approaches remain either impractical or constrained, for example, they often depend on the availability of a

Why this matters
Why now

The proliferation of edge devices and increasing privacy concerns are driving the need for more efficient and secure federated learning methodologies.

Why it’s important

This development in one-shot federated learning significantly reduces communication costs and privacy risks, making AI deployment more practical and scalable across distributed datasets.

What changes

Traditional iterative federated learning is being challenged by more efficient single-round approaches, enabling broader adoption in sensitive or resource-constrained environments.
