WebSeems the easiest way to do this in pytorch geometric is to use an autoencoder model. In the examples folder there is an autoencoder.py which demonstrates its use. The gist of it is that it takes in a single graph and tries to predict the links between the nodes (see recon_loss) from an encoded latent space that it learns. Webmolecules are particularly amenable to graph representations. Specifically, molecules can be represented as graphs with nodes representing the atoms and edges representing …
