Unsuperivised learning for graph classification?

[karthickai]

Hi all, Greetings. Could someone point me to a code example for using Unsupervised GraphSAGE or different architectures to generate node embeddings for downstream graph classification tasks?

Check out this example.

Yes, I have seen this example already. However, this example doesn't suit for downstream graph classification tasks because it uses LinkNeighborLoader for the Cora dataset. Is there any direct example code to use the MUTAG kind of dataset for unsupervised learning using graphSAGE for graph classification? Thanks.

You can still use the obtained node embeddings for a downstream task by aggregating them together and applying an MLP on top.
