Can you speak a little more about how those work? I understand word embeddings conceptually. And I can imagine using a similar process to embed the arbitrary data stored in a graph. Embedding an entire graph makes less sense to me, unless 'entire graph' means a subgraph of the general population.
I do social network stuff occasionally. If I hypothetically could create an embedding representation of everyone, I could imagine it might be useful to, say, TSNE it all as opposed to a force layout for viz. Or maybe run it as a pretty black box prediction input? Wondering if I'm missing something more obvious here
