Sinusoidal embeddings背后的含义是告诉model,我们试图在哪个时间步骤预测noise。通过注入model在noise schedule中的位置信息(positional information),来帮助model预测每个时间步骤的噪声。例如,我们有一个noise schedule,在某些时间步骤有大的noise,model理解哪些时间步必须要预测,将会帮助它预测相应时间
之前一直在看一些Diffusion的工作,不论是文字版的还是视频版的,但一直没有时间对这里面的原理做一些整理,最近看到了 https://www.tonyduan.com/diffusion/index.html里面关于Diffusion的相关工作,对其整理的内…

A diffusion model in general terms is a type of generative deep learning model that creates data from a learned denoising process. There are many variations of diffusion models with the most popular ones usually being text conditional models that can generate a certain image based on a prompt. ...
In How Diffusion Models Work, you will gain a deep familiarity with the diffusion process and the models which carry it out. More than simply pulling in a pre-built model or using an API, this course will teach you to build a diffusion model from scratch
稳定扩散模型的原名是潜扩散模型(Latent Diffusion Model, LDM)。正如它的名字所指出的那样,扩散过程发生在潜在空间中。这就是为什么它比纯扩散模型更快。潜在空间首先训练一个自编码器,学习将图像数据压缩为低维表示。通过使用训练过的编码器E,可以将全尺寸图像编码为低维潜在数据(压缩数据)。然后通过使用经过训练的...

We start by training a small-sized latent diffusion model (LDM) from scratch, but observe a significant fidelity drop in the synthetic images. Through a thorough assessment, we find that DPM is in- trinsically biased against high-frequency generation, and learns to recover different frequency ...
扩散(采样)过程会迭代地向U-Net提供完整尺寸的图像获得最终结果。这使得纯扩散模型在总扩散步数T和图像大小较大时极其缓慢。 稳定扩散就是为了解决这一问题而设计的。 稳定扩散 Stable Diffusion 稳定扩散模型的原名是潜扩散模型(Latent Diffusion Model, LDM)。正如它的名字所指出的那样,扩散过程发生在潜在空间中。这...
