  • Patent number: 12254412
    Abstract: A neural network pruning system can sparsely prune neural network models using an optimizer based approach that is agnostic to the model architecture being pruned. The neural network pruning system can prune by operating on the parameter vector of the full model and the gradient vector of the loss function with respect to the model parameters. The neural network pruning system can iteratively update parameters based on the gradients, while zeroing out as many parameters as possible based a preconfigured penalty.

  • Publication number: 20240193877
    Abstract: Various embodiments described herein provide a virtual production system that comprises a set of skin machine-learning models, a set of upper-body machine-learning models, a memory storing instructions, and one or more hardware processors to perform several operations based on stored instructions. Operations can comprise receiving a first image depicting a three-dimensional figure in a posing position and dressed in select apparel. Operations can comprise using the set of skin machine-learning models to generate a second image, where the set of skin machine-learning models up-sample the skin of the three-dimensional figure to generate photorealistic skin. Also, operations can comprise using the set of upper-body machine-learning models to generate a third two-dimensional image, where the set of upper-body machine-learning models up-sample an upper portion of the three-dimensional figure to generate a photorealistic upper portion.

  • Patent number: 11657479
    Abstract: A mobile device can implement a neural network-based domain transfer scheme to modify an image in a first domain appearance to a second domain appearance. The domain transfer scheme can be configured to detect an object in the image, apply an effect to the image, and blend the image using color space adjustments and blending schemes to generate a realistic result image. The domain transfer scheme can further be configured to efficiently execute on the constrained device by removing operational layers based on resources available on the mobile device.
