Muon Algorithm Gains New Convergence Guarantees and Variants

Researchers have established new theoretical convergence guarantees for the Muon algorithm, a method used in machine learning. By employing a more accurate proxy for the Newton-Schultz iteration, they demonstrated that Muon's iterates converge to a zero gradient under specific hyperparameter choices. The study also introduced "Muesterov," a Nesterov-based variant of Muon, which extends the theoretical framework and offers similar convergence properties. Numerical experiments on a cross-entropy problem and preliminary simulations with the nanoGPT dataset support the theoretical findings and suggest practical applicability. AI
