English(EN) Ori: Drift-Aware Streaming $k$-PCA for Very Low-Rank LLM Training

Ori 优化器通过漂移感知 k-PCA 缩小 LLM 训练差距

研究人员开发了 Ori,一种用于训练大型语言模型 (LLM) 的新优化技术,解决了低秩训练的挑战。Ori 使用受 Oja++ 启发的漂移感知流式 k-PCA 算法,持续跟踪变化的梯度主方向。这种方法显著缩小了低秩和全秩 LLM 训练之间的性能差距,在 LLaMA 预训练任务上取得了高达 69.3% 的改进,并在 Roberta-Base 微调任务上优于其他方法。 AI

影响 这项研究可能导致更高效、更准确的大型语言模型训练,从而降低计算成本并提高各种自然语言处理任务的性能。

    Ori: 漂移感知流式 $k$-PCA 用于极低秩 LLM 训练

    arXiv:2610.22794v1 Announce Type: new Abstract: A prominent family of low-rank LLM optimizers, pioneered by GaLore, performs gradient-subspace projection: at each step, they project the gradient into a low-dimensional subspace and map the update back to the full model. Most exist…
