DeFoG: Discrete Flow Matching for Graph Generation

1 code implementation5 Oct 2024 Yiming Qin, Manuel Madeira, Dorina Thanou, Pascal Frossard

We also theoretically demonstrate that, for general discrete data, discrete flow models can faithfully replicate the ground truth distribution - a result that naturally extends to graph data and reinforces DeFoG's foundations.

Sparse Training of Discrete Diffusion Models for Graph Generation

1 code implementation3 Nov 2023 Yiming Qin, Clement Vignac, Pascal Frossard

Generative graph models struggle to scale due to the need to predict the existence or type of edges between all node pairs.

Class-Balancing Diffusion Models

1 code implementation CVPR 2023 Yiming Qin, Huangjie Zheng, Jiangchao Yao, Mingyuan Zhou, Ya zhang

To tackle this problem, we set from the hypothesis that the data distribution is not class-balanced, and propose Class-Balancing Diffusion Models (CBDM) that are trained with a distribution adjustment regularizer as a solution.
