  • Patent number: 11568061
    Abstract: Training of a model is performed to minimize expected loss under noise (ELUN) while maintaining differential privacy. Noise is added to weights of a machine learning model as random samples drawn from a noise distribution, the noise being added in accordance with a privacy budget. The ELUN is minimized by using a loss function that anticipates noise added to the weights of the machine learning model, to find a point in the parameter space for which loss is robust to the noise in the weights. The addition of noise and the minimization of the ELUN are iterated until the weights converge and optimization constraints are satisfied. The model is utilized on arbitrary inputs while protecting the privacy of training data used to train the model.

  • Patent number: 11543922
    Abstract: Techniques enabling improved classification of touch or hover interactions of objects with a touch sensitive surface of a device are presented. A speaker of the device can emit an ultrasonic audio signal comprising a first frequency distribution. A microphone of the device can detect a reflected audio signal comprising a second frequency distribution. The audio signal can be reflected off of an object in proximity to the surface to produce the reflected audio signal. A classification component can determine movement status of the object, or classify the touch or hover interaction, in relation to the surface, based on analysis of the signals. The classification component also can classify the touch or hover interaction based on such ultrasound data and/or touch surface or other sensor data. The classification component can be trained, using machine learning, to perform classifications of touch or hover interactions of objects with the surface.

  • Patent number: 11531369
    Abstract: An exemplary embodiment of a user interface display panel includes a top or cover glass layer which extends to the perimeter of the panel housing. A touch-sensitive display layer is adhered to the bottom surface of cover glass layer to form a touch sensitive display assembly and is just smaller in area than that of the cover glass layer to provide a peripheral lip region for adherence to a waterproof gasket to bond the cover glass and display layer to the housing structure. The display layer is supported above the surface of the tub wall. The arrangement results in an active touch-sensitive display area significantly larger than display areas provided in the past by interface panels.
