Graph level prediction
WebThe most common edge-level task in GNN is link prediction. Link prediction means that given a graph, we want to predict whether there will be/should be an edge between two nodes or not. For example, in a social network, this is used by Facebook and co to propose new friends to you. Again, graph level information can be crucial to perform this task.
