Improving Diffusion Posterior Samplers with Lagged Temporal Corrections for Image Restoration
Researchers have developed new methods to improve diffusion models for various inverse problems. One approach, AVIS, uses autoregressive diffusion models to accelerate video restoration, significantly reducing latency and increasing throughput. Another development, LAMP, enhances diffusion posterior samplers by incorporating lagged temporal corrections for image restoration tasks. Additionally, Stein Diffusion Guidance (SDG) offers a training-free framework for posterior correction, enabling more effective guidance in low-density regions for tasks like image generation and protein docking.
