About Node2vec #6

Closed Littlepijiang closed 1 year ago

Littlepijiang commented 2 years ago

Hi，it is my understanding that the graph embedding model Node2vec applies to homogeneous graphs. You employ Node2vec to generate user embedding matrix and item embedding matrix, I want to know if in this work the different nodes and edges are treated as the same nodes and edges?

Littlepijiang commented 2 years ago

Different nodes and edges here mean different types of nodes and edges in heterogeneous graph.

fengzhu1 commented 2 years ago

Yes, in this work, we treat them as the same nodes. Maybe, it will get better representations of users and items if you adopt something more appropriate.
