GNNs Meet Sequence Models Along the Shortest-Path: an Expressive Method for Link Prediction
SP4LP encodes a candidate link by feeding the GNN embeddings of nodes on the shortest path between its endpoints into a sequence model, and claims provable expressiveness gains over prior GNN link predictors.
