Researchers have introduced Reflective Flow Sampling (RF-Sampling), a novel inference enhancement technique specifically designed for text-to-image diffusion models that utilize flow matching algorithms. Unlike previous methods that primarily target conventional diffusion models, RF-Sampling is theoretically grounded and requires no additional training. It enhances generation quality and prompt alignment by performing implicit gradient ascent on the text-image alignment score, exploring noise spaces more consistent with the input prompt. AI
