Is Your Conditional Diffusion Model Actually Denoising?

arXiv — cs.LGTuesday, December 23, 2025 at 5:00:00 AM
  • Recent research has highlighted that conditional diffusion models, widely used in generative image modeling and control policies, often deviate from the idealized denoising process they are based on, leading to inconsistencies in generation outcomes. The study introduces a measure called Schedule Deviation to quantify this deviation and demonstrates that it occurs regardless of model capacity or training data.
  • This finding is significant as it challenges the assumptions underlying the effectiveness of current diffusion models, suggesting that improvements are necessary to align their performance with theoretical expectations.
  • The implications of this research resonate within the broader context of AI model development, where the pursuit of efficiency and accuracy continues to drive innovation. The introduction of methods like Duo in discrete diffusion models and the exploration of flow matching from a denoising perspective indicate an ongoing effort to refine generative processes and address existing limitations in the field.
