CoRe-GNN advances graph neural network training with multilevel message passing

Researchers have introduced CoRe-GNN, a novel approach to training Graph Neural Networks (GNNs) on large graphs. This method addresses memory constraints by performing both coarsened inter-cluster message passing for long-range structure and local intra-cluster message passing for node discriminability simultaneously within each layer. CoRe-GNN demonstrates improved performance over existing methods like graph coarsening and Cluster-GCN on various node classification benchmarks, maintaining memory efficiency through a new batching scheme suitable for graphs with millions of nodes.
