A new research paper explores the geometric properties of optimizers in machine learning, proposing that row normalization can outperform Adam and Muon in high-dimensional multiclass classification tasks. The study suggests that row normalization's class-wise Euclidean geometry better preserves decision-boundary directions compared to Adam's coordinate-wise geometry and Muon's spectral geometry, which can introduce distortions. This advantage is demonstrated under various data models, including isotropic Gaussian-cloud data and power-law spectra, with synthetic and language model experiments supporting the findings. AI
