Efficient Score Pre-computation for Diffusion Models via Cross-Matrix Krylov Projection

arXiv — cs.CVTuesday, November 25, 2025 at 5:00:00 AM
  • A novel framework has been introduced to enhance the efficiency of score-based diffusion models by employing a cross-matrix Krylov projection method. This approach converts the standard stable diffusion model into the Fokker-Planck formulation, significantly reducing computational costs associated with solving large linear systems for image generation. Experimental results indicate a time reduction of 15.8% to 43.7% compared to traditional sparse solvers, with a speedup of up to 115 times over DDPM baselines in denoising tasks.
  • This development is crucial as it addresses the computational challenges faced by researchers and practitioners in the field of artificial intelligence, particularly in image generation tasks. By optimizing the training process for diffusion models, the framework allows for the production of high-quality images under fixed computational budgets, which is essential for practical applications in various industries, including gaming, film, and virtual reality.
  • The introduction of this framework aligns with ongoing efforts to improve the scalability and efficiency of generative models in AI. Similar advancements, such as the SCALEX framework for exploring latent spaces and the Warm Diffusion model for blending diffusion paradigms, highlight a trend towards more automated and efficient methodologies in the field. These innovations reflect a broader movement within AI research to enhance model performance while managing computational resources effectively.
