Researchers have introduced Nora, a novel optimizer designed to enhance the efficiency, stability, and speed of training Large Language Models (LLMs). Unlike previous optimizers that often compromise on one of these aspects, Nora aims to satisfy all three requirements simultaneously. It achieves stability by projecting row-wise momentum and approximates structured preconditioning by leveraging the block-diagonal dominance of the Transformer Hessian, all while maintaining optimal computational complexity.
