LLM表示的几何结构与语言数据可用性相关

研究人员发现,大型语言模型(LLMs)中低资源语言和高资源语言之间的性能差异与其内部表示的几何特性有关。一项对30种语言的比较研究发现,LLMs在数据量较少的语言的最终层中表现出表示退化。为解决此问题,研究人员探索了在持续预训练过程中使用几何正则化技术,发现这些方法可以成功减少退化,并提供边际性能改进,尤其是在最具挑战性的任务上。 AI

影响 确定了LLM中低资源语言性能差距的几何基础,为有针对性的改进提供了新途径。

    低资源语言表示的几何学

    arXiv:2608.23358v1 Announce Type: new Abstract: The performance gap between low- and high-resource languages in LLMs is widely known, but it remains unclear which internal model factors drive these disparities. In this paper, we characterise this gap through the lens of represent…
