step2: 这一步对应于图1中的“diffusion”。根据diffusion model的前向公式(即q(xt∣x0)=N(xt;α¯tx0,(1−α¯t)I)),我们给step1中得到的x0′加上t=T/2时刻的噪声,得到xT/2。 step3: 这一步对应于图1中的“denoise”。我们将step2中得到的x_{T/2}丢进diffusion models的逆过程,并从T/2...

A diffusion model is a deep neural network that holdslatent variablescapable of learning the structure of a given image byremoving its blur(i.e., noise). After a model’s network is trained to “know” the concept abstraction behind an image, it can create new variations of that image. ...
But what is the diffusion model? A diffusion model is a type of generative machine-learning model that transforms random noise into realistic data by iteratively refining it. Here examples include PixelCNN++ for image generation, GPT-3.5 for text generation, and RealNVP for density estimation. ...
