  • Publication number: 20240107495
    Abstract: During operation, a computer system may provide instructions to access points in an indoor environment to measure relative distances between the access points. Then, the computer system may receive the measured relative distances. Moreover, the computer system may calculate geographic locations of the access points based at least in part on the measured relative distances. Next, the computer system may select potential anchor access points in the access points, and may provide, to an electronic device, information specifying the potential anchor access points. Furthermore, the computer system may receive, from the electronic device, second information specifying anchor access points in the potential access points and defined locations of the anchor access points. Additionally, the computer system may update the geographic locations based at least in part on the defined of the anchor access points, and may provide, to the access points, the updated geographic locations.

  • Publication number: 20230376724
    Abstract: Methods, systems and media for explaining a basis for a binary inference task performed by a neural network. Binary relationships are identified between features detected by the trained neural network and data samples in which those features are detected. Sets of features providing an inference context are then identified in tandem with sets of features providing the inference basis within a given inference context. Each context, basis pair potentially provides an explanation for the inference behavior of the neural network. Human perceptible representations of such pairs are generated to explain the inference behavior of the neural network, including automatically identifying similar samples sharing both the context and basis, and automatically identifying likely alternative samples sharing the context but not the basis.
