感悟 看完图卷积一代.二代,深感图卷积的强大,刚开始接触图卷积的时候完全不懂为什么要使用拉普拉斯矩阵( $L=D-W$),主要是其背后的物理意义.通过借鉴前辈们的论文.博客.评论逐渐对图卷积有了一定的了解,作为一个刚上研的博士生,深感得对图神经网络进行一个系统的学习. 本篇论文得感谢论文 David I Shuman 作者及博主:纯牛奶爱酸牛奶 Paper Information Authors:D. Shuman, S. Narang, P. Frossard, Antonio Ortega,…

Cracking the Coding Interview(Trees and Graphs) 树和图的训练平时相对很少,还是要加强训练一些树和图的基础算法.自己对树节点的设计应该不是很合理,多多少少会有一些问题,需要找一本数据结构的书恶补一下如何更加合理的设计节点. ? class TreeNode { public: int treenum; TreeNode** children; int child_num; int child_len; in…

We can choose between two standard ways to represent a graph as a collection of adjacency lists or as an adjacency matrix. Either way appliesto both directed and undirected graphs. Because the adjacency-list representationprovides a compact way to re…
