Training Unbiased Diffusion Models from Biased Datasets: A Time-Dependent Approach


title_rewrite


The author proposes time-dependent importance reweighting to mitigate bias in diffusion models, leading to improved sample quality and proportion. By utilizing the time-dependent density ratio for reweighting and score correction, the objective function becomes tractable, converging to an unbiased data distribution.
