Abstract: Systems and methods are described for automating retrieval of application data prior to wireless network outages and rendering mobile device UIs during the outages. The system includes a server and database of data object files corresponding to features of applications executable on the mobile device. The mobile device receives a notification from the server before a predicted network outage, and sends back a request including parameters indicating resource status. The mobile device receives a response including a data object file from the database and automatically invokes a network bot, UI bot, and navigation bot. The network bot retrieves application data from a web server based on an object from the data object file. The navigation bot generates a navigation handle based on an object from the data object file, and the UI bot renders a UI based upon a UI object from the data object file and the navigation handle.

Abstract: Previous neural network models that perform named entity recognition (NER) typically treat the input sentences as a linear sequence of words but ignore rich structural information, such as the coreference relations among non-adjacent words, phrases, or entities. Presented herein are novel approaches to learn coreference-aware word representations for the NER task. In one or more embodiments, a “CNN-BiLSTM-CRF” neural architecture is modified to include a coreference layer component on top of the BiLSTM layer to incorporate coreferential relations. Also, in one or more embodiments, a coreference regularization is added during training to ensure that the coreferential entities share similar representations and consistent predictions within the same coreference cluster. A model embodiment achieved new state-of-the-art performance when tested.

Abstract: A system can include one or more processors that determine a first position of an object in view of a user of a head mounted display (HMD) and a first gaze direction towards the first position. The object can be detected by one or more sensors. The one or more processors detect that the user is gazing at the object. The one or more processors determine, responsive to detecting that the user is gazing at the object, a second gaze direction based on at least a second position of one or more eyes of the user of the HMD provided via an eye tracking operation of the HMD. The one or more processors calibrate, based at least on a difference between the first gaze direction and the second gaze direction, the eye tracking operation of the HMD.
