Abstract: Apparatuses, systems, and techniques to train one or more neural networks using stratified sampled training data parameters. In at least one embodiment, one or more stochastic training data parameters may be stratified sampled from one or more sampling ranges to compute a gradient for updating the one or more neural networks.

Abstract: Approaches presented herein provide systems and methods to reuse a rendered image for noising and denoising steps used for training one or more content generation systems. The reused rendered image may reduce computationally expensive processes, such as content generation and rendering, and enable multiple gradients to be compared using a common image that may be noised and then processed by one or more diffusion models to compute a gradient. The gradients may be combined and used to retrain the model, providing more training data with less variance between generating and rendering steps.
