TrasMuon: Trust-Region Adaptive Scaling for Orthogonalized Momentum Optimizers

Peng Cheng, Jiucheng Zang, Qingnan Li +6

Muon-style optimizers leverage Newton-Schulz (NS) iterations to orthogonalize updates, yielding update geometries that often outperform Adam-series methods. However, this orthogona…
