新的二次模型改进了希普定律对词类型-标记关系的描述

作者 PulseAugur 编辑部 · [1 个来源] ·

研究人员提出了一种对希普定律的二次项修正。希普定律传统上使用幂函数描述词类型和标记之间的关系。虽然希普定律在双对数尺度上是线性的，但经验观察显示出轻微的凹性。新的二次模型在英语小说上进行了测试，更准确地拟合了类型-标记数据，其线性系数略高于1，二次系数约为-0.02。该形式化方法还提供了一种使用“伪方差”概念估计曲率的方法，尽管在大标记数下可能面临数值不稳定性。 AI

    Heaps' Law 的二次项修正

    arXiv:2511.14683v2 Announce Type: replace Abstract: Heaps' or Herdan's law characterizes the word-type vs. word-token relation by a power-law function, which is concave in linear-linear scale but a straight line in log-log scale. However, it has been observed that even in log-log…
