研究：日语和英语共享LLM神经元，但因果关系较弱

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-22 14:31

研究人员调查了一个双语大型语言模型（LLM）llm-jp-3-1.8B内部表示是否共享日语和英语。他们使用在模型层上训练的稀疏自动编码器（SAE）来分析特征相关性，并通过消融特征进行因果检验。虽然相关性表明跨语言的名称和概念存在共享特征，但因果检验仅显示出较弱的共享因果关系证据，主要出现在日语中。 AI

影响为理解LLM中的跨语言表示提供了见解，可能有助于开发更有效的双语AI系统。

Do Japanese and English Share Neurons? I Trained the Microscope to Check

<p><em>Sparse autoencoders find human-readable features inside LLMs. I trained one per layer on a Japanese-English model and measured which features fire in both languages — then tested whether they actually matter, with controls. The correlation is beautiful. The causation is bo…
