WebGraph Isomorphism Network 标签: 深度学习 Paper : GRAPH ISOMORPHISM NETWORK\nCode :\n\n摘要\n作者使用Weisfeiler-Lehman(WL) test 和同构图判定问题来评估GNN网络的表达能力,并提出了GIN网络结构,理论分析GIN的表达能力优于GraphSAGE GCN等结构,在多任务上准确率达到了SOTA。 Web论文:HOW POWERFUL ARE GRAPH NEURAL NETWORKS? 作者:Keyulu Xu,Weihua Hu, Jure Leskovec 来源:ICLR 2024 1. 概括. GNN目前主流的做法是递归迭代聚合一阶邻域表征来更新节点表征,如GCN和 GraphSAGE,但这些方法大多是经验主义,缺乏理论去理解GNN到底做了什么,还有什么改进空间。. 本文基于Weisfeiler-Lehman(WL) test 视角 …

There exists a function f: X → R n so that h ( X) = ∑ x ∈ X f ( x) is unique for each multiset X ⊂ X of bounded size. Moreover, any multiset function g can be decomposed as g ( X) = ϕ ( ∑ x ∈ X f ( x)) for some ... WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior.
