新条件核史坦因差异框架用于分布比较

研究人员引入了一个名为条件核史坦因差异(CKSD)的新框架,用于评估数据集的条件分布与目标条件模型匹配的程度。该方法通过在协变量空间上使用算子值核来扩展现有的核史坦因差异(KSD),即使在协变量分布未知的情况下也能进行比较。所提出的统计量仅当条件模型与真实条件分布在大多数协变量上对齐时才会消失,并且已被证明在光滑流形和离散空间上进行测试是可行的。 AI

影响 引入了一种新的分布比较统计方法,可能有助于模型评估和开发。

    arXiv:2610.11863v1 Announce Type: cross Abstract: Kernel Stein discrepancies (KSDs) provide a versatile tool for comparing distributions. One of their main applications is in quantifying the goodness-of-fit (GoF) between a data-generating distribution and a prescribed target dist…
