  • Publication number: 20260094372
    Abstract: One embodiment sets forth a technique for generating virtual objects. According to some embodiments, the technique includes generating, based on object data, compressed object data; performing, based on the compressed object data, one or more operations to train an untrained machine learning model to generate a trained machine learning model that comprises a trained decoder, where the trained machine learning model is trained to generate a reconstruction of the compressed object data; and generating, based on one or more conditions, a predicted virtual object using a trained diffusion model and the trained decoder.

  • Publication number: 20260003885
    Abstract: A model visualization system analyzes model behavior to identify clusters of data instances with similar behavior. For a selected feature, data instances are modified to set the selected feature to different values evaluated by a model to determine corresponding model outputs. The feature values and outputs may be visualized in an instance-feature variation plot. The instance-feature variation plots for the different data instances may be clustered to identify latent differences in behavior of the model with respect to different data instances when varying the selected feature. The number of clusters for the clustering may be automatically determined, and the clusters may be further explored by identifying another feature which may explain the different behavior of the model for the clusters, or by identifying outlier data instances in the clusters.
