Researchers have developed a new framework called GP-Refiner to accelerate Diffusion Transformers, a dominant paradigm in generative AI. This plug-and-play method uses Gaussian Process Regression to dynamically correct deviations that arise from prediction-based feature caching, a common technique for speeding up these models. By treating full computation steps as noisy observations and monitoring posterior variance, GP-Refiner adaptively calibrates computations. Experiments show significant improvements, with one integration reducing computational load by over 19% while enhancing image quality metrics. AI
