该文章讨论了一种基于谱方法的图神经网络(Spectral Graph Neural Network, Spectral GNN),主要围绕其表达能力进行理论分析,并提出了一种新的模型——JacobiConv。 1.背景 图神经网络(GNN) 是图结构数据上的一种表示学习方法,在各类任务中表现优异。谱GNN在频谱域中设计图信号滤波器,与空间GNN(Spatial GNN)不同,它...
How Powerful are Spectral Graph Neural Networksarxiv.org/abs/2205.11172 1. Preliminaries 任意矩阵表示为 M∈Ra×b,MAB,A→rowindexset,B→columnindexset ,克洛内克积 δij ,矩阵的 condition number κ(M)=|λmax|/|λmin| ,因此如果是一个奇异矩阵,对应 κ(M)=+∞。 定义一个排列组合运算 π ...
空域图神经网络通常采用消息传递的框架,在节点域通过传播图上的局部信息来学习有用的图表示;谱域图神经网络则通过图滤波器在频谱域对特征进行滤波,通常能够学习到非局部的信息。一个更详细的讨论可以见论文“A Survey on Spectral Graph Neural Networks”。虽然空域图神经网络已经在许多领域取得了令人印象深刻的表现,...

Variants of Graph Neural Networks (GNNs) for representation learning have been proposed recently and achieved fruitful results in various fields. Among them, Graph Attention Network (GAT) first employs a self-attention strategy to learn attention weights for each edge in the spatial domain. However,...
