Implementation of unsupervised GNN

[jianchaoji]

Do we have other implementation of unsupervised GNN model, other than the given example :graph_sage_unsup.py
Such as unsupervised GCN and GAT

We have a few more:

• examples/node2vec.py
• examples/autoencoder.py
• examples/link_pred.py
• examples/infomax.py

Thank you for your reply! Is there any plan to update unsupervised GCN and GAT ? If no can I send you a PR when I implement my unsupervised GCN and GAT examples?

[rusty1s]

I'm not exactly sure what you mean with unsupervised GCN. For example, the unsupervised autoencoder.py example already utilizes GCN, and the infomax.py examples utilizes GAT.

Oh,I didn't recogenize that since the loss function is different from graph_sage_unsup. Thanks for your explanation！
