Higher-Order Guided Diffusion for Graph Generation: A Coarse-to-Fine Approach to Preserving Topological Structures

Understanding Graph Generation Challenges

Graph generation is complicated. It involves creating structures that accurately represent relationships between different entities. Many existing methods struggle to capture complex interactions needed for applications like molecular modeling and social network analysis. For example, diffusion-based methods, initially meant for image creation, often lose vital topological details, leading to unrealistic graphs.

Problems with Current Methods

Traditional approaches often disrupt important characteristics, like sparsity and connectivity, by adding noise to adjacency matrices. This results in a loss of structural integrity. Additionally, current models like recurrent neural networks and variational autoencoders are expensive and lack scalability. Diffusion-based frameworks have been introduced but are primarily designed for continuous data, failing to maintain the unique characteristics of graph structures.

The HOG-Diff Solution

HOG-Diff offers a new approach to graph generation that addresses these issues. It uses a systematic, step-by-step process to maintain essential topological features. This involves creating higher-order graph skeletons and refining relationships without losing detail.

Key Features of HOG-Diff

  • Coarse-to-Fine Learning: Breaks down the generation into manageable steps, ensuring detailed preservation of structure.
  • Intermediate Steps: Uses a diffusion bridge mechanism for organized transitions between stages.
  • Spectral Diffusion: Injects noise in a way that maintains connectivity patterns, leading to more coherent outputs.
  • Advanced Architecture: Combines graph convolutional networks and transformer networks to capture both local and global relationships effectively.

Proven Performance

Extensive testing shows that HOG-Diff outperforms existing methods in generating both molecular and generic graphs. In molecular applications, it achieves high similarity measures, indicating a strong alignment with real-world molecular distributions. Its ability to maintain advanced structures results in graphs that are realistic and stable.

Why Choose HOG-Diff?

This innovative approach integrates higher-order structural information directly into the graph generation process, ensuring topological fidelity. It has been validated on diverse datasets, making it suitable for various applications, including drug discovery and urban modeling.
