Nodes with no Node Features for GCNs.

❓ Questions & Help

Say I have a Graph, with Nodes which doesn't hold individual Node Features. How can I pass it through a GCNs?

In case no node features are given, you have multiple options:

1. You can use synthetic node features like node degree, e.g., via transforms.OneHotDegree()
2. You can use the identity matrix as input node features.
3. You can use learnable embeddings for each node via torch.nn.Embedding. The first option is a good choice in inductive training scenarios, while the latter two are good choices in transductive/semi-supervised learning tasks.
