Researchers have introduced Nora, a novel matrix-based optimizer designed for efficient and stable training of large language models. Nora aims to unify efficiency, stability, and speed, addressing limitations of existing methods like Muon and RMNP. The optimizer stabilizes weight norms and angular velocities, approximates structured preconditioning, and achieves a computational complexity of O(mn), with a simple two-line implementation. AI
