Muon - Wikipedia
It is classified as a lepton. As with other leptons, the muon is not thought to be composed of any constituent particles. The muon is an unstable subatomic particle with a mean lifetime of 2.2 μs.

GitHub - KellerJordan/Muon: Muon is an optimizer for hidden layers in ...
Muon is an optimizer for the hidden weights of a neural network. Other parameters, such as embeddings, classifier heads, and hidden gains/biases should be optimized using standard AdamW.
About Muons – MuonSources
The muon technique involves implanting spin-polarised positive muons into a material, where they undergo decay and release positrons. The positrons are analysed to understand the muon’s …
[2502.16982] Muon is Scalable for LLM Training - arXiv.org
Feb 24, 2025 · We identify two crucial techniques for scaling up Muon: (1) adding weight decay and (2) carefully adjusting the per-parameter update scale. These techniques allow Muon to work out-of-the …
