Research Paper Overview
LiMuon: Light and Fast Muon Optimizer for Large Models
Summary
Large models in AI require efficient training. LiMuon is a light and fast Muon optimizer designed for matrix-structured parameters in large models. It uses momentum-based variance reduction and randomized SVD to reduce memory usage and sample complexity to O(ε^-3) for non-convex stochastic optimization under smooth and generalized smooth conditions. LiMuon outperforms existing Muon variants in memory efficiency and convergence guarantees. Experiments on DistilGPT2 and ViT models demonstrate its training efficiency.
