谱图理论 (Spectral Graph Theory) 通过对拉普拉斯矩阵进行谱分解 (Spectral Decomposition),我们可以得到矩阵的本征值 (eigenvalue) 和本征矢 (eigenvector)。根据谱定理 (Spectral Theory),我们知道一个 n\times n 的对称矩阵有 n 个实本征值, \lambda_1\leq\lambda_2\leq...\leq\lambda_n n 个实本征...

深度学习图论(Graph Theory) 1.图论(Graph Theory) 1.1 什么是图(graph)? 在图论的上下文中,图是一种结构化数据类型,具有节点(nodes)(保存信息的实体)和边缘(edges)(连接节点的连接,也可以保存信息)。 图是一种数据结构的方式,但它本身可以是一个数据点。图是一种非欧几里得数据类型,这意味着它们存在于三维空...

graph theory and infinite graphs. At the end of each chapter, there is a section with exercises and another with bibliographical and historical notes. Many of the exercises were chosen to complement the main narrative of the text: they illus- trate new concepts, show how a new invariant ...

opportunity to explain some methods in sparse extremal graph theory. These methods have migrated to the connectivity chapter, where they now live under the roof of the new proof by Thomas and Wollan that 8kn edges make a 2k-connected graph k-linked. So they are still there, leaner than eve...

We propose a new type of supervised visual machine learning classifier, GSNAc, based on graph theory and social network analysis techniques. In a previous study, we employed social network analysis techniques and introduced a novel classification model (
Notes 1. See The Truth about Königsberg by Brian Hopkins and Robin J. Wilson in the May 2004 issue, of The College Mathematics Journal for a nice discussion of Euler’s argument. Euler’s paper (and lots more) is in Graph Theory: 1736–1936 (Oxford University Press, 1976) by Norman...
