Where Do Crystal Graph Networks Fail? A Space-Group-Resolved Error Analysis of Band Gap Prediction with a Simple Edge-Aware GNN: Crystal-X
This study presents a space-group-, centering-type-, and band gap-resolved error analysis of GNN band gap prediction on the Materials Project dataset, and argues that this kind of granular, symmetry-resolved evaluation should accompany aggregate benchmarks when assessing crystal GNNs.
