Muon 优化器谱整形分析揭示低维度的益处

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-07 04:00

研究人员调查了细粒度谱整形对于 Muon 优化器的必要性，该优化器使用矩阵动量结合当前和过去的梯度。通过谱诊断，他们发现大部分奇异模式位于估计的噪声边缘之下，但集体上与参考梯度呈正相关。该研究引入了 BulkBoost，一个双频带谱重加权框架，该框架在与现有方法竞争的同时，通过降低最终损失而优于 Muon 的标准平坦配置文件。 AI

影响这项研究可能通过改进优化技术，从而实现更高效的 AI 模型训练。

Muon 是否需要精细的光谱整形？

arXiv:2610.07497v1 Announce Type: new Abstract: Muon combines current and past gradients into matrix momentum. For $M=U\Sigma V^\top$, the idealized polar update $Q=UV^\top$ gives every singular direction the same weight. We refer to this as the flat profile. Several recent optim…
