In the previous lesson, we introduced the mathematical foundation of Graph Convolutional Networks (GCNs). You can find the explanation of the GCN formula in the following link: [link below].https://medium.com/@staytechrich/graph-convolutional-networks-gcn-001-understanding-the-gcn-formula-step-by-step-a5e248c91ce0Now, we will implement a GCN model in PyTorch, applying the concepts we learned. We..
