  • Publication number: 20190155284
    Abstract: Methods, computer-readable media, and devices are disclosed for improving an object model based upon measurements of physical properties of an object via an unmanned vehicle using adversarial examples. For example, a method may include a processing system capturing measurements of physical properties of an object via at least one unmanned vehicle, updating an object model for the object to include the measurements of the physical properties of the object, where the object model is associated with a feature space, and generating an example from the feature space, where the example comprises an adversarial example. The processing system may further apply the object model to the example to generate a prediction, capture additional measurements of the physical properties of the object via the at least one unmanned vehicle when the prediction fails to identify that the example is an adversarial example, and update the object model to include the additional measurements.

  • Patent number: 10154295
    Abstract: A system that incorporates the subject disclosure may perform operations, for example, including determining a first correlation value between a behavior of a first audience member and a subject matter being presented at a display processor, wherein the subject matter being presented at the display is observable by the first audience member. A second correlation value is determined between the behavior of the first audience member and a characteristic of an environment in a vicinity of the display and the first audience member. Responsive to the second correlation value exceeding the first correlation value, a determination is made as to whether a present channel selection resulting from user input initiated by the first audience member is responsive to the characteristic of the environment influencing the audience member more than the subject matter being presented at the display. Other embodiments are disclosed.

  • Publication number: 20180336440
    Abstract: In one example, the present disclosure describes a device, computer-readable medium, and method for performing event monitoring in an unconstrained manner using a network of drones. For instance, in one example, a first video and a second video are obtained. The first video is captured by a first drone monitoring a first field of view of a scene, while the second video is captured by a second drone monitoring a second field of view of the scene. Both the first video and the second video are unlabeled. A deep learning technique is applied to the first video and the second video to learn a model of the scene. The model identifies a baseline for the scene, and the deep learning technique is unsupervised. The model is stored.
