新的自适应对数空间量化提高了LLM优化器的内存效率

研究人员开发了一种名为自适应对数空间(AL)的新量化方法,以提高训练大型语言模型时使用的优化器的内存效率。该方法为每个块自适应量化范围,并保持精确零不变性,与现有的低精度技术相比,提供了更好的状态重构误差控制。在TinyLlama-1.1B和GPT-2等模型上的评估表明,在对困惑度或损失影响极小的情况下,优化器状态存储显著减少,这表明了一种更具拓扑感知的优化器量化方法。 AI

影响 这项研究通过减少优化器的内存需求,有可能在现有硬件上训练更大的模型。

    超越稠密Adam状态:用于内存高效优化器的自适应对数空间量化

    arXiv:2608.22322v2 Announce Type: replace Abstract: Low-precision optimizer-state methods are commonly designed and evaluated for dense Adam-style first and second moments. Memory-efficient optimizers depart from this setting: Adafactor factorizes second moments, CAME adds factor…
