Gophormer: Ego-Graph Transformer for Node Classification 1. Gophormer是什么? Gophormer是一种图神经网络(GNN)模型,专门用于节点分类任务。它结合了Transformer架构和ego-graph的概念,旨在克服传统GNN在处理大型图时的可扩展性问题和长距离依赖捕获能力不足的局限。Gophormer通过为每个节点生成一个ego-graph(自我图)...
Introduction全局注意机制将整个输入图视为一个全连通的图,并融合了来自所有节点的信息,这可能会引入来自许多无关的长距离邻居的噪声。最后但并非最不重要的是,与具有少量可学习参数的gnn不同,变压器包含更多…
ego_graph(G, n, radius=1, center=True, undirected=False, distance=None) 返回在给定半径内以节点n为中心的邻域的诱导子图。 参数 G ( 图表 )--…

Based on this review and our experiments, we propose our own method which leverages the social graph's topology and differences in egographs of legitimate and fake user accounts to improve identification of the latter. We evaluate our approach against other common approaches on a real-world ...
目录 收起 subgraph egonet motif 和graphlet subgraph 一个biggraph中的部分节点和边构成的子图。 egonet 所谓的ego network,它的节点是由唯一的一个中心节点(ego),以及这个节点的邻居(alters)组成的,它的边只包括了ego和alter之间,以及alter与alter之间的边,如下图: 其中,图里面的每个alter和它自身的邻居...
