The forward diffusion process gradually adds Gaussian noise to the image, adding only a tiny bit of noise at each step, and the noising process is controlled by a fixed variance schedule (such as linear or cosine scheduling) and involves no learnable parameters.

VerifiedDiffusion models circumvent the instability of adversarial training through a Markov chain mechanism that progressively adds Gaussian noise and then trains the model to learn the reverse denoising process.76% 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.76% similarVerified扩散模型通过在海量图像数据上训练，学会了从随机噪声中逐步去噪生成图像的能力76% similarVerifiedDiffusion models are inspired by non-equilibrium thermodynamics and employ a two-step training process: the forward process gradually adds Gaussian noise to an image until it becomes pure random noise, and the reverse process trains a neural network to progressively denoise from pure noise back to a clear image.76% similar
