Summary
A recent study published on arXiv has explored the spectral scaling laws of the Muon optimizer, which is utilized in large language models. The researchers focused on the singular value spectrum of momentum matrices and discovered that the late layers of the model exhibit aggressive scaling as the model size increases. This finding indicates that modifications to the Newton-Schulz iteration process for orthonormalization are necessary to accommodate these scaling behaviors effectively.
Takeaways
