Abstract: A computing environment includes multiple client devices that may each be configured to serve a particular function within the computing environment. The client devices are each coupled to a client management server that communicates with and manages functions of the client devices. When a client device first boots, the client management server communicates with the client device over a network in order to provision the client device with an enrollment image. Using the enrollment image, a client device can become enrolled with the client management server. Once enrolled, the client management server can provision the client device with a functional operating system image. The functional operating system image can support device applications that require a restricted number of runtime states within the client device. A new functional operating system image is downloaded from the client management server and installed on the client device each time the device is rebooted.

Abstract: An online system accesses a model attribute store, which stores configuration information and model performance scores for a plurality of models, each model used to predict performance metrics regarding content from a third party system presented to users of the online system. The online system trains a meta-model classifier using the models in the model attribute store, the meta-model classifier trained to predict, for a candidate model, a predicted model performance score of that candidate model. The online system also generates a plurality of candidate models for input to the meta-model classifier, each of the plurality of candidate models including a distinct set of configuration information. The predicted model performance scores for a selected candidate model in the plurality of candidate models is computed using the meta-model classifier, and the online system transmits a report to the third party system indicating predicted model performance score for the selected candidate model.

Abstract: A video system processes video frames from a wide angle camera to dewarp the video frames in a manner that preserves conformity of an object of interest. A crop region of a video frame corresponding to the object of interest is determined. An input parameter to a dewarping function is generated based on the detected crop region. The dewarping function is applied to the crop region using the input parameter to generate a dewarped video frame and the dewarped video frame is outputted. The input parameter may be generated in a manner that causes the dewarped video frame to have higher conformity and lower distortion in the region around the object of interest than in a region distant from the object of interest.
