English(EN) Speculating LLMs' Chinese Training Data Pollution from Their Tokens

研究:LLM显示Token造成显著的中文数据污染

一篇新的研究论文提出了一种方法来检测和分析大型语言模型(LLM)中的“被污染的中文”(PoC)Token。这些Token通常与色情或网络赌博相关,发现在许多LLM中普遍存在,其中GPT模型表现最差,显示超过40%的长中文Token属于这些类别。该研究在C4和Pile等数据集上验证了其推测方法,并估计与“波多野结衣”相关的内容可能占GPT-4o训练数据的约0.5%。 AI

影响 凸显了LLM训练数据中潜在的偏见和有害内容,需要改进数据策展和过滤。

    推测LLMs的中文训练数据因其Token而受到污染

    arXiv:2508.17771v3 Announce Type: replace Abstract: Tokens are basic elements in the datasets for LLM training. It is well-known that many tokens representing Chinese phrases in the vocabulary of GPT (4o/4o-mini/o1/o3/4.5/4.1/o4-mini) are indicating contents like pornography or o…
