去噪扩散概率模型(Denoising Diffusion Probabilistic Models, DDPM)在没有对抗训练的情况下实现了高质量的图像生成,但其需要多步模拟马尔可夫链(Markov chain)才能生成样本。为加速采样,我们提出了去噪扩散隐式模型(Denoising Diffusion Implicit Models, DDIM),这是一类更有效的迭代隐式概率模型,其训练过程与 DDPM 相同...

Diffusion models are also applied to many low-level vision tasks. For instance, DDRM [19] per- forms diffusion sampling in the spectral space of degradation operator A to reconstruct the missing information in the ob- servation y. DDNM [64] shares a similar id...
DDIM原理及代码(Denoising diffusion implicit models) 前言 之前学习了 DDPM(DDPM原理与代码剖析)和 IDDPM(IDDPM原理和代码剖析), 这次又来学习另一种重要的扩散模型。它的采样速度比DDPM快很多(respacing),扩散过程不依赖马尔科夫链。 Denoising diffusion implicit models, ICLR 2021...
DDIM(Denoising Diffusion Implicit Models)作为这一研究领域的关键突破,对于优化采样过程和提升采样速度具有重大意义。特别是在文生图和文生视频的应用背景下,DDIM的高效采样能力显著提高了这些先进技术的实用性和可达性。——AI Dreams, APlayBoy Teams! 论文阅读:https://arxiv.org/pdf/2010.02502.pdf ...
