PromptLoop: Plug-and-Play Prompt Refinement via Latent Feedback for Diffusion Model Alignment
Suhyeon Lee, Jong Chul Ye
Despite recent progress, reinforcement learning (RL)-based fine-tuning of diffusion models often struggles with generalization, composability, and robustness against reward hacking…
Single-Step Bidirectional Unpaired Image Translation Using Implicit Bridge Consistency Distillation
Suhyeon Lee, Kwanyoung Kim, Jong Chul Ye
Unpaired image-to-image translation has seen significant progress since the introduction of CycleGAN. However, methods based on diffusion models or Schrödinger bridges have yet to…
UNICORN: Ultrasound Nakagami Imaging via Score Matching and Adaptation
Kwanyoung Kim, Jaa-Yeon Lee, Jong Chul Ye
Nakagami imaging holds promise for visualizing and quantifying tissue scattering in ultrasound waves, with potential applications in tumor diagnosis and fat fraction estimation whi…
OTSeg: Multi-prompt Sinkhorn Attention for Zero-Shot Semantic Segmentation
Kwanyoung Kim, Yujin Oh, Jong Chul Ye
The recent success of CLIP has demonstrated promising results in zero-shot semantic segmentation by transferring muiltimodal knowledge to pixel-level classification. However, lever…
