Muse: Representation Geometry of Muon Beyond Normalized Momentum

Da Chang, Qiankun Shi, Lvgang Zhang +4

The paper investigates how the choice of matrix representation influences Muon-style optimizers, proposes the Muse family of optimizers that keep the same momentum and Newton–Schul…

A Note on Stability for Orthogonalized Matrix Momentum with Client Sampling

Da Chang, Qiankun Shi, Lvgang Zhang +2

We study finite-sample generalization for a client-sampled distributed optimization scheme with matrix-valued parameters and orthogonalized momentum updates. The central quantity i…

MuonEq: Balancing Before Orthogonalization with Lightweight Equilibration

Da Chang, Qiankun Shi, Lvgang Zhang +5

Orthogonalized-update optimizers such as Muon improve training of matrix-valued parameters, but existing extensions typically either rescale updates after orthogonalization or use…

When Does Value-Aware KV Eviction Help? A Fixed-Contract Diagnostic for Non-Monotone Cache Compression

Ruijie Zhang, Haozhe Liang, Da Chang +4

Long-context LLM inference is bottlenecked by the memory and bandwidth cost of reading large KV caches during decoding. KV compression reduces this cost by keeping only part of the…
