New GO-MUON method refines spectral geometry for optimization

Researchers have introduced GO-MUON, a novel optimization method that enhances the accuracy of muon's polar update by employing a matched data-dependent geometry. This approach precisely solves weighted spectral oracles, irrespective of how the geometry maps are estimated or refreshed. The study also analyzes the backward factor's approximation to model Fisher and generalized Gauss-Newton factors for softmax cross-entropy, and explores the trade-offs of a four-step refresh process.

    Second-Order Muon Done Right: A Principled Marriage of Spectral Geometry and Curvature

    arXiv:2608.09763v1 Announce Type: new Abstract: Muon's polar update is exact for an unweighted spectral geometry. We introduce GO-MUON, which uses a matched data-dependent geometry and reuses it across several optimization steps. Conditioned on any positive-definite left and righ…
