Diffusion基础---DDPM:Tutorial on Diffusion Models for Imaging and Vision 读书笔记系列(2) 之后的第三部分,这一部分主要介绍DDIM。 Denoising Diffusion Implicit Model (DDIM) DDPM(扩散概率模型)的一个主要缺点是,反向过程需要太多步以实现去噪。这会使得生成图像的速度变得十分缓慢(在一块标准GPU上,DDPM需要超过...
前言:看论文发现需要补Diffusion基础,读了《Tutorial on Diffusion Models for Imaging and Vision》,个人感觉写挺好,比目前很多博文都更容易理解。于是准备写一个系列的读书笔记,希望不要像上一个系列烂尾。…
[LG] Tutorial on Diffusion Models for Imaging and Vision http://t.cn/A6Tq09if 本教程全面系统地介绍了从变分自编码器到扩散模型的发展脉络,数学推导细致,内容丰富,是理解扩散模型的好教材。
Diffusion magnetic resonance imaging (dMRI) is a versatile imaging technique that has gained popularity thanks to its sensitive ability to measure displacement of water molecules within a living tissue on a micrometer scale. Although dMRI has been around since the early 1990s, its applications are...

One caveat is that these models can be time-consuming to build, sample from, and validate, especially when models include links between neural activations and model parameters. Here we describe a novel extension to the widely used hierarchical drift diffusion model (HDDM) toolbox, which ...
