Verified扩散模型的核心原理分为前向扩散过程（逐步添加高斯噪声）和反向去噪过程（从噪声中还原图像）两个阶段78% similarUnverifiedDiffusion models typically require dozens to hundreds of denoising steps when generating images, with each step having a U-Net or Transformer network predict the noise component.75% similarVerifiedThe core idea of diffusion models originates from non-equilibrium thermodynamics: during the training phase, Gaussian noise is gradually added to clear images, and during the inference phase, noise is progressively removed from random noise in reverse to restore the image.74% similar
