Abstract: Examples disclosed herein provide the ability for a computing device to adjust settings on a computing device. In one example method, the computing device captures, via a first sensor of a computing device, images of an environment that the computing device is currently in, and detects objects in the environment as captured by the images. As an example, the computing device determines a location of the environment based on contextual data gathered from the detected objects and adjusts a setting on the computing device based on the determined location.

Abstract: For each of a number of workloads, time intervals within execution performance information that was collected during execution of the workload on a first hardware platform are correlated with corresponding time intervals within execution performance information that was collected during execution of the workload on a second hardware platform. For a workload, the time intervals within the execution performance information on the second hardware platform are correlated to the time intervals within the execution performance information the first hardware platform during which the same parts of the workload were executed. A machine learning model that outputs predicted performance on the second hardware platform relative to known performance on the first hardware platform is trained. The model is trained from the correlated time intervals within the execution performance information for each workload on the hardware platforms.

Abstract: A communication system may include, in an example, a first computing device communicatively coupled, via a network, to at least a second computing device maintained at a geographically distinct location than the first computing device; the first computing device including: an array of audio output devices and a processor to receive transmitted speech data and metadata describing an estimated direction of arrival (DOA) of speech from a plurality of speakers at an array of microphones at the second computing device and render audio at the array of audio output devices associated with the first computing device by eliminating spatial collision during rendering; said spatial collision arising due to the low angular separation of the estimated DOA of a plurality of speakers.

Abstract: Acoustic echo cancellation for a video conference system is described. A location of a person in a room can be determined. An audio signal received from the location of the person can be captured using beamforming. An acoustic echo cancellation parameter can be determined based in part on the audio signal captured from the location of the person. Acoustic echo cancellation can be performed on the audio signal using the acoustic echo cancellation parameter.

Abstract: A system for exposure control of captured images includes a processor, a memory device communicatively coupled to the processor, a first image capture device located within a space and communicatively coupled to the processor, a second image capture device located within the space and communicatively coupled to the processor, a plurality of electromagnetic wave sources located within the space, and an illumination module stored on the memory device and executable by the processor. the illumination module activates the first image capture device to capture an image of a subject, and coordinate the plurality of electromagnetic wave sources to illuminate the subject based on the location of the first image capture device relative to the subject and the location and an orientation of each of the electromagnetic wave sources.

Abstract: A location of a first wireless device relative to a second wireless device with which the first wireless device exchanges an in-band data stream is determined. The in-band data stream is exchanged via a wireless signal, and the location is determined based at least in part on an out-of-band data stream originating at the first wireless device. A direction toward which to steer a beam of radiation emitted by an antenna array of the first wireless device is determined based on the location. An instruction is then transmitted to the first wireless device. The instruction instructs the first wireless device to steer the beam toward the direction.
