新方法为图曲率计算提供更紧密的下界

研究人员开发了一种新方法,用于建立 Ollivier-Ricci 曲率(ORC)的更紧密下界。ORC 是一种用于捕捉图中几何信息的方法。这种新界限在保持比计算精确 ORC 低得多的计算成本的同时,显著改进了现有近似值。该方法对 1 跳和 k 跳随机游走都有效,在各种图结构上的实验中证明了其准确性和效率。 AI

影响 这项研究可能带来更有效的图分析技术,并可能影响那些依赖于理解复杂网络结构的 AI 应用。

    基于残差壳的 Ollivier-Ricci 曲率下界

    arXiv:2604.12211v2 Announce Type: replace Abstract: Ollivier-Ricci curvature (ORC), defined via the Wasserstein distance that captures rich geometric information, has received growing attention in both theory and applications. However, the high computational cost of Wasserstein d…
