English(EN) Beyond the Lower-Star Filtration: Alternative Filtration Methods for Persistent Homology

新的过滤方法增强了持久同调分析

研究人员为持久同调引入了三种新颖的过滤方法:ε-下星过滤(ELSF)、Lp过滤(LpF)和softmax过滤(SMF)。这些方法旨在通过修改单纯形过滤值的分配方式来克服标准下星过滤(LSF)的局限性。与LSF不同,LSF可能导致高维单纯形与其边界面同时进入过滤,而新方法引入了延迟或使用考虑所有顶点值的聚合函数。这种渐进式进入允许拓扑特征持续更长时间,可能揭示更多用于数据人口区分的信息。实验表明,这些新方法在计算效率上更高,并且比LSF对结构化数据差异更敏感。 AI

影响 这些新的过滤方法可以改进复杂数据集的分析,可能有助于识别与机器学习任务相关的细微结构差异。

    超越低星过滤:持久同调的替代过滤方法

    arXiv:2611.08833v1 Announce Type: new Abstract: In the lower-star filtration (LSF), simplices are assigned filtration values according to the maximum-vertex rule, with each simplex entering the filtration when its highest-valued vertex appears. A limitation of this construction i…
