Diffusion基础---VAE:Tutorial on Diffusion Models for Imaging and Vision 读书笔记系列(1)后的第二部分,这一部分主要介绍DDPM。 Denoising Diffusion Probabilistic Model (DDPM) 上一节我们讲解了VAE的本质:将难以处理的(intractable)图像分布 p(x) 映射到一个易处理的(tractable) 分布 p(z) (如高斯分布 N(...
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。这个系列中,尽可能略过推导,旨在说明每个公式的意义。 Variational Auto-Encoder (VAE) VAE的概览 VAE的本质是...
1. VAE: VAE的基础结构建立在潜在变量 z 的概率分布上，其中 p(z) 通常选择为高斯分布 N(0, I)。VAE的训练和推理依赖于 Evidence Lower Bound (ELBO)，即通过与先验分布的匹配来估计编码器的 KL 散度。2. Denoising Diffusion Probabilistic Model: DDPM的核心在于从一个状态到另一个状态的过渡，...
[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。
In this task, we will play with diffusion models to generate 2D images. We first look into some background of DDPM and then dive into DDPM in a code level.BackgroundFrom the perspective of SDE, SGM and DDPM are the same models with only different parameterizations. As there are forward ...

Diffusion models can be used to infer cognitive processes involved in fast binary decision tasks. The model assumes that information is accumulated continuously until one of two thresholds is hit. In the analysis, response time distributions from numerous trials of the decision task are used to esti...
