VerifiedDiffusion 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.85% 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.82% similarVerifiedThe denoising process of diffusion models is based on the DDPM principle, which involves progressively adding Gaussian noise to data during training and then training a neural network to learn the reverse denoising process.80% similarUnverified扩散模型的训练过程分为加噪与去噪两个阶段，推理阶段的条件可引入额外视觉信号（如参考视频、深度图、骨骼图）约束去噪方向80% similarUnverifiedDRaFT利用扩散模型去噪过程的可微性，将奖励函数梯度直接回传至模型参数，无需强化学习的策略梯度估计器，规避高方差问题79% similar
