WebBuilding a Graph Convolutional Network. This article is an introductory tutorial to build a Graph Convolutional Network (GCN) with Relay. In this tutorial, we will run our GCN on Cora dataset to demonstrate. Cora dataset is a common benchmark for Graph Neural Networks (GNN) and frameworks that support GNN training and inference. WebThe graph convolutional network (GCN) was first introduced by Thomas Kipf and Max Welling in 2024. A GCN layer defines a first-order approximation of a localized spectral filter on graphs. GCNs can be understood as a generalization of convolutional neural networks to graph-structured data. The formal expression of a GCN layer reads as follows:
