Abstract: The present disclosure relates to a system, a method, and a product for intent discovery. The system includes a processor in communication with a memory storing instructions. When the processor executes the instructions, the instructions are configured to cause the processor to: obtain documents comprising a set of utterances, extract the set of utterances from the documents, generate a set of utterance embeddings based on the set of utterances, clusterize the set of utterance embeddings to obtain a plurality of clusters, obtain a cluster label for each cluster, encode each document based on a number of times each utterance cluster identifier (ID) appears to obtain an encoded document, perform latent Dirichlet allocation (LDA) on the encoded documents to obtain K topics, and each topic corresponding to a list of key clusters with cluster IDs, and for each topic, replace the cluster IDs with the cluster labels.

Abstract: A three-dimensional (3D) mapping system can be configured to generate a 3D map of a real-world environment using annotation of large image data sets, in which terrestrial imagery can be programmatically labeled with accurate labels using remotely sensed overhead image data. The 3D mapping system can implement photogrammetry to create a point cloud. Each pixel in the point cloud can be classified based on a consensus of each frame. The point cloud can be co-registered to a remotely sensed reference dataset to provide precise spatial coordinates for each pixel. Different patches of point clouds can be stitched together to provide a complete 3D map for a given area, such as a downtown area of a city.

Abstract: Accuracy of Global Navigation Satellite System (GNSS) for GNSS devices is improved using a GNSS positioning system that leverages networked optimization for enhanced accuracy. GNSS measurements from multiple devices form the foundation for a massive pairwise optimization approach. This fuels a self-reinforcing cycle, wherein Real Time Kinematic (RTK) pairwise optimizations support Precise Point Positioning (PPP) analysis. Improved PPP calculations in turn refine RTK optimization, rapidly iterating towards convergence. The PPP-RTK feedback loop refines positions iteratively, culminating in more accurate user locations.

Abstract: Systems and methods are used for providing mapping, data management and analysis. Data for at least two different data sets can be accepted. A vector density analysis of each data set can be performed using: temporal analysis, intersection analysis, spatial concentration analysis, or spatial correlation analysis. Each loaded data set can rastorized. Each rasterized data set can be converted to a certain scale. A convolution operation can be performed on each converted data set. Convolution results can be applied to a color ramp. Each map can be created based on the color ramp and the convolution results. A combination map illustrating where the at least two different data sets intersects each other can be created. Proximity and magnitude of the at least two different data sets can be illustrated.
