• Abstract: Diffusion models are learning pattern-learning systems to model and sample from data distributions with three functional components namely the forward process, the reverse process, and the sampling process. The components of diffusion models have gained significant attention with many design factors being considered in common practice. Existing reviews have primarily focused on higher-level solutions, covering less on the design fundamentals of components. This study seeks to address this gap by providing a comprehensive and coherent review of seminal designable factors within each functional component of diffusion models. This provides a finer-grained perspective of diffusion models, benefiting future studies in the analysis of individual components, the design factors for different purposes, and the implementation of diffusion models.

  Given the same starting noise input and a deterministic sampler, different diffusion models often yield remarkably similar outputs. We show that diffusion models are learning distinct distributions affected by the training data size. This valuable property generalizes to many variants of diffusion models, including those for conditional use, solving inverse problems, and model fine-tuning.
