Rethinking Message Passing Neural Networks with Diffusion Distance-guided Stress Majorization
PositiveArtificial Intelligence
- A new model for message passing neural networks (MPNNs), named DDSM, has been introduced to address issues such as over-smoothing and over-correlation that plague existing models. This innovative approach utilizes stress majorization and orthogonal regularization, along with diffusion distances for nodes, to enhance message passing operations and includes efficient algorithms for distance approximations, supported by rigorous theoretical analyses.
- The development of DDSM is significant as it demonstrates a marked improvement over 15 strong baselines in both homophilic and heterophilic graphs, indicating its potential to advance the effectiveness of learning on graph-structured data, which is crucial for various applications in artificial intelligence.
