GraphGDP: Generative Diffusion Processes for Permutation Invariant Graph Generation

Huang, Han, Sun, Leilei, Du, Bowen et al.

Understand

Graph generative models have broad applications in biology, chemistry and social science.

  • However, modelling and understanding the generative process of graphs is challenging due to the discrete and high-dimensional nature of graphs, as well as permutation invariance to node orderings in underlying graph distributions.
  • Current leading autoregressive models fail to capture the permutation invariance nature of graphs for the reliance on generation ordering and have high time complexity.
  • Here, we propose a continuous-time generative diffusion process for permutation invariant graph generation to mitigate these issues.
