Node2Vec embeddings to global graph features

Question

I want to extract global features for input graphs. I thought about using node2vec to build embeddings for each node of a graph. How can I use these node embeddings to come up with global features for the graphs? Does averaging the embeddings of all the nodes in a graph and considering the resulting vector the feature vector of the graph seem appropriate?

Answer 1

The embedding themselves, are learned in the same way as word2vec’s embeddings are learned using a skip-gram model.

If you post which explains it in great detail as from this point forward I assume you are familiar with it.are familiar with the word2vec skip-gram model, great, if not I recommend this great

The most natural way I can think about explaining node2vec is to explain how node2vec generates a “corpus” and if we understand word2vec we already know how to embed a corpus.

So how do we produce this corpus from a graph? That’s exactly the innovative part of node2vec and it does so in an intelligent way which is done using the sampling strategy.
