Hi @mgao97 ,
The common PyG dataset is a standard graph but not a hypergraph right? If I remember correctly, our shape [2, 9170] corresponds to the star-expansion bipartite graph for the considered hypergraph. See either my reply in #13 or our paper for detail on what is a star-expansion and the corresponding bipartite graph.
Best, Eli
Hi~
I have another question about the 'edge_index' of the original Data object.
Taking the CoauthorshipCora dataset as an example, why the size of the edge_index of it is [2, 9170], which is not correspond to the widely used values used in torch-geometric dataset object like [2, 5429].
Could you please give some illustrations on how to get it for a new dataset?
