Researchers have investigated how training diffusion transformers on downscaled images affects gradient signals. They found that while a downscaled latent can preserve most of the surviving signal at high noise levels, the training gradient signal is influenced by both a noise-dependent term and a floor term related to the target grid's token count. This analysis led to the identification of specific noise windows and downscaling routes where training with reduced resolution maintains gradient accuracy, enabling a 14.6% reduction in training time for LoRA adapters.
