Abstract: Methods, systems, and devices for techniques for dynamically adjusting retransmission opportunities within a connected isochronous stream (CIS) are described. In some aspects, a first wireless device and a second wireless device may support one or more dynamic or “on-the-fly” adjustments to one or more CIS settings in accordance with a link quality between the first wireless device and the second wireless device. For example, the first wireless device and the second wireless device may tie a number of transmission opportunities that are usable for retransmissions, within a given isochronous (ISO) interval, to the link quality between the first wireless device and the second wireless device. The link quality may be tied or associated with a modulation and coding scheme (MCS) of the link. As such, the first wireless device and the second wireless device may tie a dynamic change in MCS to a dynamic change in retransmission opportunities.

Abstract: A method, computer program, and computer system is provided for testing a user interface. A previously trained machine learning model trained with traces of interactions between one or more users and a user interface is accessed. The interactions include one or more timestamps of user interactions with the user interface, actions by each user associated with the user interface, and metadata associated with user interactions. A simulated interaction of a simulated agent utilizing the user interface is generated using the previously trained machine learning model. The simulated interaction is encoded as an input trace to a user interface. The encoded simulated interaction is input into the user interface for automated testing of the user interface. Results of the automated testing of the user interface are received.

Abstract: In federated learning problems, data is scattered across different servers and exchanging or pooling it is often impractical or prohibited. A Bayesian nonparametric framework is presented for federated learning with neural networks. Each data server is assumed to provide local neural network weights, which are modeled through our framework. An inference approach is presented that allows us to synthesize a more expressive global network without additional supervision, data pooling and with as few as a single communication round. The efficacy of the present invention on federated learning problems simulated from two popular image classification datasets is shown.
