Muon optimizer's speedup may harm generalization, study finds

A new research paper analyzes the optimization algorithm Muon, which has gained popularity for its faster training speeds compared to Adam. The study reveals that Muon achieves its speed by avoiding saddle points, but this comes at the cost of a simplicity bias found in Gradient Descent. This loss of simplicity bias can lead Muon to struggle with identifying underlying structures across tasks and potentially fit spurious features, suggesting that faster optimization may not always be beneficial for generalization.
