WebSep 18, 2024 · What is a Graph Convolutional Network? GCNs are a very powerful neural network architecture for machine learning on graphs. In fact, they are so powerful that even a randomly initiated 2-layer GCN can produce useful feature representations of … WebThe GNN classification model follows the Design Space for Graph Neural Networks approach, as follows: Apply preprocessing using FFN to the node features to generate initial node representations. Apply one or more graph convolutional layer, with skip connections, to the node representation to produce node embeddings.
