Efficient Diffusion Models: A Survey
It addresses the problem of computational inefficiency in diffusion models for researchers and practitioners in AI and digital content creation, but it is incremental as it compiles existing work without introducing new methods.
This survey systematically reviews research on efficient diffusion models, which are powerful generative models but face high computational costs and slow generation times, aiming to provide a comprehensive resource for researchers and practitioners.
Diffusion models have emerged as powerful generative models capable of producing high-quality contents such as images, videos, and audio, demonstrating their potential to revolutionize digital content creation. However, these capabilities come at the cost of their significant computational resources and lengthy generation time, underscoring the critical need to develop efficient techniques for practical deployment. In this survey, we provide a systematic and comprehensive review of research on efficient diffusion models. We organize the literature in a taxonomy consisting of three main categories, covering distinct yet interconnected efficient diffusion model topics from algorithm-level, system-level, and framework perspective, respectively. We have also created a GitHub repository where we organize the papers featured in this survey at https://github.com/AIoT-MLSys-Lab/Efficient-Diffusion-Model-Survey. We hope our survey can serve as a valuable resource to help researchers and practitioners gain a systematic understanding of efficient diffusion model research and inspire them to contribute to this important and exciting field.
