Lookahead Sample Reward Guidance for Test-Time Scaling of Diffusion Models

Researchers present LiDAR, a test-time scaling method for diffusion models that improves sample quality alignment with human intent using efficient reward guidance. The approach achieves comparable performance to existing gradient guidance methods while delivering 9.5x faster sampling speeds by computing expected future rewards from marginal samples without neural backpropagation.

Training-Free Reward-Guided Image Editing via Trajectory Optimal Control

Researchers have developed a new training-free framework for reward-guided image editing using diffusion models. The approach treats image editing as a trajectory optimal control problem, allowing for better preservation of source image content while enhancing target rewards compared to existing methods.
