At its core, N-GCN trains multiple instances of GCNs over node pairs discovered at different distances in random walks, and learns a combination of the instance outputs which optimizes the classification objective. Our experiments show that our proposed N-GCN model improves state-of-the-art ...

LPGNet通常能达到最佳效果,并提供比DpGCN更好的攻击弹性,同时提供类似或更好的实用程序。我们的关键见解是摆脱传统的GNN /GCNs,其中原始图边(邻接矩阵)是神经网络架构不可分割的一部分。提供DP的传统方法,如DpGCN中使用的方法,会极大地改变邻接矩阵,并且在添加噪声后,会严重扭曲GCN内部的传播结构。相反,我们建议将...
To predict categorical labels of the nodes in a graph, you can use a GCN [1]. For example, you can use a GCN to predict types of atoms in a molecule (for example, carbon and oxygen) given the molecular structure (the chemical bonds represented as a graph). ...

image dataset. Results demonstrate that the GLCNN can improve the accuracy of the semi-supervised node classification by mining useful relationships among nodes. The performance is more obvious especially on datasets of Euclidean space. Specifically, GLCNN outperforms the best baseline by 3.1% and ...
no general network-oriented methodology has been proposed yet to perform node classification. In this paper we propose a three-stage classification framework that effectively deals with the typical very large size of such datasets. The stages are: (1) top node weighting, (2) projection to a wei...
