arXiv:2607.00173v1 Announce Type: new Abstract: Federated learning is bandwidth-bound on two orthogonal axes: model size, which limits how often parameter-averaging methods can afford to merge, and class count, which makes per-probe soft-label distillation prohibitive at large vocabularies. Both ceilings tighten as modern systems scale. We collapse the class-count axis to $\lceil \log_2 C \rceil$ bits per probe by transmitting only each peer's $\arg\max$ class index, where $C$ is the number of output classes. The resulting protocol, TallyTrain, is not merely compressed: under non-IID training
The increasing scale of modern AI systems and the growing need for distributed, privacy-preserving machine learning necessitate more efficient communication protocols.
This development addresses critical bandwidth limitations in federated learning, making it more practical for large-scale, real-world applications across various sectors.
Federated learning can now be applied more effectively to models with large class counts and in bandwidth-constrained environments, reducing communication overhead significantly.
