  • Publication number: 20250076059
    Abstract: A technique for interacting with map-related information integrates the use of a machine-trained language model. Upon submission of a query, the technique uses the machine-trained language model to assess at least one intent associated with the query. The technique then invokes an intent-specific processing flow to provide an output result. Each processing flow invokes the use of at least one processing engine to perform an engine-specific task, such as geocoding, route finding, or image retrieval. A processing flow can also call on the machine-trained language model one or more additional times. In some cases, the technique includes a feedback mechanism for soliciting additional information from a user.

  • Publication number: 20240410706
    Abstract: A technique generates estimated time-of-arrival (ETA) information to assist in navigating from one physical location to another. The technique uses a computer-implemented route-finding engine to identify a route between a specified starting location and an ending location of a trip. The route includes a sequence of segments. The technique then uses a machine-trained model to map information regarding the segments to ETA information. The ETA information provides an estimate of a time-of-arrival for the trip as a whole. The ETA information also provides an estimate of parameters that describe the level of confidence of the time-of-arrival estimate for the trip. A training system produces the machine-trained model using a loss function, part of which models the time-of-arrival for the trip as a mixture of distributions.

  • Patent number: 11877159
    Abstract: Described herein are technologies relating to assigning wireless beacons to positions within a building, wherein the wireless beacons are included in an indoor positioning system. A computer-implemented floorplan representation is generated, wherein the representation includes a layout of the building and materials of structures of the building. Coverages of wireless beacons are simulated, and multiple objectives are balanced to identify a number of wireless beacons to deploy in the building and positions in the building where the wireless beacons are to be deployed.

  • Patent number: 11663224
    Abstract: Technology is described herein for ranking candidate result items in at least two stages. In a first stage, the technology uses a first attention-based neural network to determine an extent of attention that each token of an input query should pay to the tokens of each candidate result item. In a second stage, the technology uses a ranking subsystem to perform listwise inference on output results provided by the first stage, to generate a plurality of ranking scores that establish an order of relevance of the candidate results items. The ranking subsystem may use a second attention-based neural network to perform the listwise inference. According to some implementations, the technology is configured to process queries and candidate result items having different kinds and combinations of features. For instance, one kind of input query may include text-based features, structure-based features, and geographic-based features.
