Graph convolutional networks gain remarkable success in semi-supervised learning on graph-structured data. The key to graph-based semisupervised learning is capturing the smoothness of labels or features over nodes exerted by graph structure. Previous methods, spectral methods and spatial methods, devote...
在众多的嵌入方法中,基于图神经网络(Graph Neural Networks, GNN)的嵌入方法近年来备受瞩目。其中,图卷积网络(Graph Convolutional Networks, GCN)通过捕捉图中节点的邻域信息,能够有效学习节点之间的关系,是解决知识图谱嵌入问题的强大工具。 GCN 发展与基础原理 ...
A Graph Convolutional Network (GCN) is a technique used in graph neural networks that extends the convolution operation from image data processing to graph data processing. It involves creating a mapping function to extract interaction-aware features from the node features in a network and their nei...
例如Semi-Supervised Classification with Graph Convolutional Networks一文中的GCN形式,其实是二阶Chebyshev多项式推导出的特例。 在我最近发表的一篇论文中:就是用这种GCN形式作为基于有限检测器的路网规模交通流量估计问题(一种特殊的时空矩阵填充问题)的baseline,即原文4.2节部分的CGMC模型。感兴趣的朋友可以阅读如下的...
图卷积网络(GraphConvolutionalNetworks,GCNs)是图神经网络的一种,它在图结构数据上执行卷积操作。与传统的卷积神经网络(CNNs)在网格状数据(如图像)上工作不同,GCNs可以在任意结构的图上进行操作。 2.2.1图拉普拉斯矩阵 在GCNs中,图拉普拉斯矩阵(GraphLaplacian)是一个关键的概念。它定义为: L 其中,D是度矩阵,A是...
