VerifiedRepresentative products of mainstream Diffusion Models include Stable Diffusion, early versions of DALL-E 2, and Midjourney; their working principle involves progressively adding Gaussian noise to images during training and then training a neural network to learn the reverse denoising process.80% similarVerified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79% 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79% similarPartially 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.78% similarVerifiedDiffusion 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.78% similar
