Can this method be used to do subgraph matching? #11

A very nice paper. But can this method be used to do subgraph matching?

EmilyAlsentzer commented 3 years ago

The code can't do subgraph matching out of the box. Currently it's set up for subgraph classification. It assumes that you have prespecified subgraphs & associated labels that you want to predict.

However, the SubGNN architecture is generalizable and can be used for unsupervised or semi-supervised learning as well by changing the loss function. I can imagine using an approach like that used in NeuroMatch to identify query subgraphs and then using SubGNN with a semi-supervised learning objective to embed the subgraphs.

Hope this helps!
