Geometric graph neural networks are essential for modeling scientific problems with geometric features, addressing the limitations of traditional GNNs.
Zusammenfassung
Geometric graph neural networks play a crucial role in modeling scientific problems with geometric features. Unlike generic graphs, they exhibit physical symmetries that require specialized models for effective processing. Researchers have proposed various approaches to enhance the characterization of geometry and topology in geometric graphs. This comprehensive survey explores data structures, models, and applications related to geometric GNNs. It provides insights into the challenges and future directions of this field.
The content delves into the importance of incorporating symmetry into model design when dealing with geometric graphs. Various models like SchNet, DimeNet, GemNet, LieConv, SphereNet, ComENet, and more are discussed in detail. These models leverage invariant or equivariant properties to handle the unique characteristics of geometric graphs effectively. The survey also covers topics such as group theory preliminaries, equivariance/invariance definitions, and the application of geometric GNNs in molecular dynamics simulation, molecular property prediction, protein structure prediction, and more.
Performance comparisons between geometric GNNs and traditional methods on tasks like molecular property prediction, protein-ligand docking, and antibody design demonstrate the effectiveness and efficiency of geometric GNNs across various domains.
