Crystal Graph Neural Networks for Data Mining in Materials Science

1 code implementation Technical report, RIMCS LLC 2019 Takenori Yamamoto

This paper proposes crystal graph neural networks (CGNNs) that use no bond distances, and introduces a scale-invariant graph coordinator that makes up crystal graphs for the CGNN models to be trained on the dataset based on a theoretical materials database.
