Publication number: 20250217938Abstract: Weighting functions and adaptive noise distributions are provided for training a machine-learned model (e.g., image generation model) based on noised image data. A training image can be noised according to a noise distribution, which can be an adaptive noise distribution. A machine-learned model can process the noised training image to generate an output. A training system can update the machine-learned model based on a weighted loss, which can be based on the output and a weighting function. The weighting function can be monotonically non-increasing with respect to a signal-to-noise ratio. In some instances, the weighting function can have an approximately sigmoidal shape.Type: ApplicationFiled: December 18, 2024Publication date: July 3, 2025Inventors: Diederik Pieter Kingma, Ruiqi Gao
