3 Graph Convolutional Network (GCN) Motivated by conventional convolutional neural networks (CNNs) and graph embedding, a GCN is an efficient CNN variant that operates directly on graphs (Kipf and Welling,2017). For graph struc-tured data, a GCN can apply the convolution oper-ation on directly connected nodes to encode local information.

2.1 Relational graph convolutional networks Our model is primarily motivated as an extension of GCNs that operate on local graph neighborhoods (Duvenaud et al. 2015; Kipf and Welling 2017) to large-scale relational data. These and related methods such as graph neural networks (Scarselli et al. 2009) can be understood as special cases of

For example, convolution neural networks (CNNs) achieve a promising performance in many computer vision [18] and natural language processing [19] applications.

Graph Convolutional Neural Networks: The mathe-matical foundation of GCNNs is deeply rooted in the field of graph signal processing [3, 4] and spectral graph theory in which signal operations like Fourier transform and con-volutions are extended to signals living on graphs. GCNNs emerged from the spectral graph theory, e.g., as introduced

30.09.2016 · Currently, most graph neural network models have a somewhat universal architecture in common. I will refer to these models as Graph Convolutional Networks (GCNs); convolutional, because filter parameters are typically shared over all locations in the graph (or a subset thereof as in Duvenaud et al., NIPS 2015).
