New research explores nonlinear scaling and geometric optimization for efficient LLM training

Two new research papers explore methods for more efficient training of large language models (LLMs). The first paper, "On the Nonlinearity of Learning Rate Scaling for LLM Training," investigates the limitations of current learning rate extrapolation methods and proposes that the optimal learning rate exhibits upward curvature at larger scales, which can be mitigated by focusing on effective learning rates or data extrapolation. The second paper, "Geometrically Principled Randomized Optimization for Efficient LLM Training," introduces novel algorithms, GrassWalk and GrassJump, that leverage the geometry of gradient subspaces to improve optimization efficiency, achieving state-of-the-art results on models like LLaMA and Qwen.
