UnverifiedImproved samplers such as DDIM can reduce the number of denoising steps for diffusion models to tens of steps.77% similarUnverifiedAblation experiments show that DDPM augmentation only yields gains under specific conditions, with particularly notable effects on KNN classifiers when the training data proportion is low, and overall gains depend on the specific classifier.74% similarUnverifiedDDPM等马尔可夫链调度器因每步状态完全依赖前步输出，误差累积效应强于DDIM等非马尔可夫调度器73% similarUnverifiedThe forward process of DDPM gradually adds Gaussian noise to the original data, completely transforming the data into random noise after T steps.70% similarUnverifiedRegions with different target noise levels tend to reach their respective optimal prediction performance at different training epochs, making a single global early-stopping checkpoint a forced compromise among regions of varying uncertainty.69% similar
