A new paper challenges the theoretical underpinnings of the Muon optimization algorithm, demonstrating that it does not converge on convex Lipschitz functions. The research suggests that Muon's practical success likely stems from smoothness properties not captured by this classical model. While error feedback can restore theoretical convergence, it degrades empirical performance in key deep learning tasks. AI
