Embedding propagation

🚀 The feature, motivation and pitch

Hi, it would be awesome to implement Learning Graph Representations with Embedding Propagation by Alberto Garcia-Duran, Mathias Niepert for unsupervised learning on graphs.

Motivation

It's a very useful unsupervised learning approach for learning graph representations without ground truth labels. Additionally, the approach can be extended to operate with missing features.

FYI @mniepert, @diningphil

We can definitively try to integrate this approach into PyG. Do you want to get involved into this?

@rusty1s, in a couple of months, I will hopefully have some free time and could contribute to this, yes.
