Bias mitigation in graph diffusion models
Meng Yu, Kun Zhan
Most existing graph diffusion models have significant bias problems. We observe that the forward diffusion's maximum perturbation distribution in most models deviates from the stan…

Frequency Regulation for Exposure Bias Mitigation in Diffusion Models
Meng Yu, Kun Zhan
Diffusion models exhibit impressive generative capabilities but are significantly impacted by exposure bias. In this paper, we make a key observation: the energy of predicted noisy…
