  • Publication number: 20210097387
    Abstract: A method of training a predictor to predict a location of a computing device in an indoor environment incudes: receiving training data including strength of signals received from wireless access points at positions of an indoor environment, where the training data includes: a subset of labeled data including signal strength values and location labels; and a subset of unlabeled data including signal strength values and not including labels indicative of locations; training a variational autoencoder to minimize a reconstruction loss of the signal strength values of the training data, where the variational autoencoder includes encoder neural networks and decoder neural networks; and training a classification neural network to minimize a prediction loss on the labeled data, where the classification neural network generates a predicted location based on the latent variable, and where the encoder neural networks and the classification neural network form the predictor.

  • Publication number: 20180204252
    Abstract: A computer-implemented system and method generate a representation of travel costs for an individual traveler. The method includes computing a fixed community cost component attributable to each traveler in a community, per time period, computing a fixed individual cost component for the individual traveler, per time period, and for each of a set of time periods, computing a variable individual cost component for the individual traveler. For each of the time periods in the set of time periods, the fixed community cost, fixed individual cost, and variable individual cost components are aggregated into an aggregated cost. A representation is generated for displaying the aggregated costs for the set of time periods to the individual traveler, in which the three cost components are identified.

  • Patent number: 8180367
    Abstract: Methods and apparatus to provide cluster-based fingerprinting algorithms are described. In one embodiment, m closest fingerprints from k fingerprints are determined. The k fingerprints may be determined as closest fingerprints to a scan s in a signal strength domain, where the scan s is of an environment surrounding a wireless device. The center of mass of the m fingerprints may be used to determine a location estimation for the wireless device. Other embodiments are also described.

  • Patent number: 8072496
    Abstract: A motion stabilizing techniques are described. A frame of video is represented at least by frame position information. Savitzky-Golay filtering may be applied on frame position information. The resulting filtered video may have reduced visible jitteriness.
