DART: Distillation-Aware Reparameterization for Training-Free LoRA Reuse in Few-Step Video Diffusion Models
Shihong Li, Juntao Xu, JinCao +3
Few-step distillation reduces the inference cost of image-to-video generation, but directly reusing LoRA adapters trained for long denoising trajectories can weaken their intended…

ToPO: Token-Oriented Preference Optimization for Text-to-Image Diffusion Models
Juntao Xu, Shihong Li, Hoi Fan Au +1
Diffusion models have achieved remarkable success in text-to-image generation, yet aligning their outputs with human preferences remains challenging. Diffusion-DPO learns from imag…
