New Byzantine-Robust Muon optimizer enhances distributed learning resilience

Researchers have introduced Byzantine-Robust Muon, a novel optimization method designed for distributed and federated learning environments. This method enhances robustness against adversarial behavior and data heterogeneity by employing resilient momentum orthogonalization. The study establishes theoretical convergence guarantees for both general non-convex and star-convex objectives, even without assuming the i.i.d. data distribution. Empirical evaluations on image benchmarks and a language model demonstrated that the tested Muon configuration achieved superior attacked accuracy compared to standard SGD, normalized-SGD, and a tuned AdamW baseline.
