The training objective of diffusion models is generally derived through the variational lower bound (ELBO) and ultimately simplified into a mean squared error loss predicting noise, which is the core of DDPM.

VerifiedThe 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% similarUnverifiedDiffusion model training objectives typically involve predicting noise ε or velocity field v, and the noisy input can be expressed as x_t = α_t·x_0 + σ_t·ε.78% similarUnverified过拟合的统计原理是当模型参数量相对训练数据过多时，模型会记住噪声而非学到规律76% similarUnverifiedDenoising score matching (DSM) requires that the training data must come from the target distribution, otherwise the network learns the score of the wrong distribution, which is a fundamental obstacle to applying diffusion models to lattice field theory.74% 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.73% similar
