PAST: Prompt-Adaptive Sampling Termination for Efficient Diffusion Model

Renye Yan, Jikang Cheng, You Wu +4

While diffusion models have made significant progress in text-to-image tasks, they still exhibit limitations when directly optimizing downstream objectives. Although Reinforcement…

Explore or Converge? Stage-Guided Per-Step Optimization for Diffusion Models

Renye Yan, Jikang Cheng, You Wu +4

Diffusion models have strong generative capabilities. However, their maximum likelihood training objective only focuses on reconstructing the data distribution, making it difficult…

Do Less, Achieve More: Do We Need Every-Step Optimization for RL Fine-tuning of Diffusion Models?

Renye Yan, Jikang Cheng, Shikun Sun +7

Despite strong image-generation performance, diffusion models' reconstruction objectives limit alignment with human preferences. RL enables such alignment through explicit rewards.…

PFDiff: Training-Free Acceleration of Diffusion Models Combining Past and Future Scores

Guangyi Wang, Yuren Cai, Lijiang Li +2

Diffusion Probabilistic Models (DPMs) have shown remarkable potential in image generation, but their sampling efficiency is hindered by the need for numerous denoising steps. Most…
