Dion3优化器将AI训练时间缩短高达6倍

作者 PulseAugur 编辑部 · [1 个来源] ·

研究人员开发了Dion3，这是Muon优化器的一个优化版本，旨在减少计算和通信开销。新的Gram Newton-Schulz算法，以及CuTeDSL内核和兆批处理策略，显著加快了正交化过程。Dion3在实现与Muon相当或更好的性能的同时，将优化器步进时间缩短了高达六倍，并且可以作为即插即用型替代品使用。 AI

影响 Dion3的优化可能导致更大规模AI模型的训练更快、更高效。

    Dion3：全栈正交更新

    arXiv:2608.11612v1 Announce Type: cross Abstract: The Muon optimizer incurs a significant overhead cost due to its cubic-time Newton-Schulz orthogonalization step. When weights are sharded, communication overhead compounds this computational cost, eroding the benefits of Muon in …
