Diffusion Distillation with Direct Preference Optimization for Efficient 3D LiDAR Scene Completion
AAAI 2026technical
The slow sampling speed of diffusion models hinders their application in 3D LiDAR scene completion. To address this, we propose Distillation-DPO, a novel framework that accelerates sampling through score distillation while simultaneously enhancing generation quality via preference alignment. Disti
