Muon Is Theoretically Wrong For Convolutions, But Empirically Effective

Thibaut Boissin, Thomas Massena, Mathieu Serrurier +1

Muon, an optimizer known for its efficiency, has a clear interpretation for matrix-valued updates, but convolutional kernels are stored as four-dimensional tensors. Standard implem…

From SGD to Muon: Adaptive Optimization via Schatten-p Norms

Thomas Massena, Corentin Friedrich, Mathieu Serrurier

Modern optimizers, like Muon, impose matrix-wise geometry constraints on their updates. These matrix-wise constraints can be unified under Linear Minimization Oracle (LMO) theory.…
