Limiting Over-Smoothing and Over-Squashing of Graph Message Passing by Deep Scattering Transforms
Summary
The Deep Scattering Message Passing (DSMP) neural network, introduced by Yuanhong Jiang et al. in 2026, addresses critical performance issues in traditional Graph Neural Networks (GNNs), specifically instability, over-smoothing, and over-squashing. These problems often degrade GNN performance and create a trade-off dilemma. The DSMP model leverages spectral transformation to aggregate neighboring nodes with global information, thereby enhancing the precision and accuracy of graph signal processing. The authors provide theoretical proofs demonstrating DSMP's effectiveness in mitigating these issues under specific conditions. Empirical evidence and thorough frequency analysis further support DSMP's superior ability to overcome instability, over-smoothing, and over-squashing, offering a discriminatively trained, multi-layer solution for processing graph-structured data.
Key takeaway
For Machine Learning Engineers developing Graph Neural Networks, if you encounter issues like over-smoothing or instability, consider integrating the Deep Scattering Message Passing (DSMP) architecture.
