LiMuon: Light and Fast Muon Optimizer for Large Models
Researchers have introduced LiMuon, a novel optimizer designed to enhance the efficiency of training large machine learning models. This new optimizer builds upon the existing Muon framework by incorporating momentum-based variance reduction and randomized Singular Value Decomposition. LiMuon aims to reduce both memory usage and sample complexity compared to previous Muon variants, offering theoretical guarantees for finding stationary solutions in non-convex optimization problems.
