Abstract: Systems, methods, and non-transitory computer-readable media can select a first sample set comprising one or more data elements from a dataset based on a first priority score ranking at a first time for a first analysis. A second sample set comprising one or more data elements from the dataset is selected based on a second priority score ranking at a second time for a second analysis. An evaluation subset of one or more data elements from the second sample set is determined based on a comparison of the first sample set and the second sample set. The data elements in the second sample set that are not included in the evaluation subset are not analyzed ni the second analysis.

Abstract: In one embodiment, a method includes rendering a first output image comprising one or more augmented-reality (AR) objects for displays of an AR rendering device of an AR system associated with a first user. The method further includes accessing sensor signals associated with the first user. The one or more sensor signals may be captured by sensors of the AR system. The method further includes detecting a change in a context of the first user with respect to a real-world environment based on the sensor signals. The method further includes rendering a second output image comprising the AR objects for the displays of the AR rendering device. One or more of the AR objects may be adapted based on the detected change in the context of the first user.
