En comparaison avec d'autres types de réseaux de neurones graphiques, ce type de GNN repose sur une base mathématique solide. Il est basé sur la théorie du traitement graphique du signal. Il simplifie par l'utilisation de l'approximation polynomiale de Chebyshev. Quelles fonctions un GNN peut-il remplir ?

WebGNN（图神经网络） 该节对应上篇开头介绍GNN的标题，是使用MLP作为分类器来实现图的分类，但我在找资料的时候发现一个很有趣的东西，是2024年发表的一篇为《Graph-MLP: Node Classification without Message Passing in Graph》的论文，按理来说，这东西不应该是很早之前就有尝试嘛？ WebLeveraging on spectral graph theory, we treat features of points in a point cloud as signals on graph, and define the convolution over graph by Chebyshev polynomial approximation. In particular, we update the graph Laplacian matrix that describes the connectivity of features in each layer according to the corresponding learned features, which ...
