This is crucial for refining the model to make more accurate predictions. As mentioned earlier, we can express Lvlb in terms of KL divergences. From here, When we condition the forward process x0 in Lt−1, it simplifies the form, allowing us to directly calculate all KL divergences....
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...
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)...
点击蓝色按钮“Add New Model” 如何使用models? 在Text To Image页面,点击底部的Model:Default,选择刚才导入的model,就可以使用了。 Sprite-0003 如何显示negative prompt? 在Text To Image页面,点击底部的Options,拉到最底部的negative prompt,点击Enable,就可以输入negative prompt了。
We’ve previously covered how Stable Diffusion works, but instead of images the same basic principles are used to guide the model from random noise to useful tracks of music. Just a few years ago we saw a neural network trained to generate Bach, and while it was capable of moments of ...

New stable diffusion model (Stable Diffusion 2.0-v) at 768x768 resolution. Same number of parameters in the U-Net as 1.5, but uses OpenCLIP-ViT/H as the text encoder and is trained from scratch. SD 2.0-v is a so-called v-prediction model. The above model is finetuned from SD ...
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步骤的noise。对于那些不...
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…
