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
本文实现Stable Diffusion只包括采样,不包括训练。其中,模型参数都来自pretrained model; 笔者在ddpm基础上,增加ddim采样; 水平有限,如有错误,请批评指正;前言 讨论主题 从头使用Pytorch实现Latent Diffusion Models(Stable Diffusion)。除了tokenizer外,不需要使用其它的库; 在DDPM和DDIM论文中定义diffusion model的数学知识...

最后,我们将讨论DDPM中用于图像生成的训练和推理,并在PyTorch中从头开始进行编码。 1. 生成模型的必要性 基于图像的生成模型的工作是生成相似的新图像,换句话说,是我们原始图像集的“代表”。 我们需要创建和训练生成模型,因为可以用(256x256x3)图像表示的所有可能图像的集合是巨大的。图像必须具有正确的像素值组合来...
