GraphSAGE is an incredibly fast architecture to process large graphs. It might not be as accurate as a GCN or a GAT, but it is an essential model for handling massive amounts of data. It delivers this speed thanks to a clever combination of 1/ neighbor sampling to prune the graph and 2/ fast aggregation with a … See more In this article, we will use the PubMed dataset.
