English(EN) A Token Is Not a Unit of Difficulty: Segmentation Controls Where Adaptive Computation Goes Inside a Word

研究:驱动大型语言模型自适应计算的是分词,而非难度

一篇新的研究论文挑战了这样一种假设:token是语言模型中难度均等的单位。这项研究以Qwen3和BLOOM等模型为重点,证明了单词如何被分段成token会显著影响自适应计算在单词内部的分配方式。这种分段效应因语言而异,孟加拉语的模式与英语、德语和土耳其语不同。研究表明,词内意外度(surprisal)比每token字符数更能预测这种计算分配。 AI

影响 这项研究通过更好地理解计算如何在单词内部分配,可能带来更高效的语言模型架构。

    Token 不是难度单位:分段控制着自适应计算在词语内部的走向

    arXiv:2611.00983v1 Announce Type: new Abstract: Early-exit language models decide for each token how much computation to spend, usually by stopping once the prediction is confident. Yet a token is not a fixed unit: tokenizers cut words into different numbers of pieces in differen…
