  • Publication number: 20240119685
    Abstract: The techniques disclosed herein enable systems to translate three-dimensional experiences into user accessible experiences to improve accessibility for users with disabilities. Namely, the discussed system enables users with disabilities to create and personalize objects for use in the three-dimensional experience. This is accomplished by translating and grouping components from a three-dimensional space to form an intuitive and logical hierarchy. The grouped components are then organized into an accessible user interface which a user with disabilities can navigate using simplified inputs and assistive technologies. In this way, users with disabilities can be empowered to personalize their user experience and understand a three-dimensional space in a layered, well-defined format.

  • Publication number: 20240096057
    Abstract: A computer implemented method for certifying robustness of image classification in a neural network is provided. The method includes initializing a neural network model. The neural network model includes a problem space and a decision boundary. A processor receives a data set of images, image labels, and a perturbation schedule. Images are drawn from the data set in the problem space. A distance from the decision boundary is determined for the images in the problem space. A re-weighting value is applied to the images. A modified perturbation magnitude is applied to the images. A total loss function for the images in the problem space is determined using the re-weighting value. A confidence level of the classification of the images in the data set is evaluated for certifiable robustness.

  • Publication number: 20240078768
    Abstract: Features described herein generally relate to learning and recognizing object-centered routines. Particularly, object-centered routines can be learned and recognized by collecting data corresponding to a user. The data can include information representing interactions by the user with respect to objects in an environment. The routine can be learned by presenting a visual graph to the user. The user can define nodes associating an interaction with an object, specify a relationship between nodes, and arrange the nodes into segments. The visual graph can be stored, and a routine can be recognized based on the visual graph.
