Patent number: 11954609Abstract: Concepts and technologies disclosed herein are directed to optimizing and reducing redundant dispatch tickets via a network knowledge graph. According to one aspect disclosed herein, a network knowledge graph generation system (“NKGGS”) can construct a machine learning model to determine a probability of an installation job needing a helper job to fulfill a service order. The NKGGS can execute the machine learning model to determine the probability. The machine learning model can determine the probability of the installation job needing the helper job to fulfill the service order based upon a network knowledge graph and a dependency score. The NKGGS can cluster the installation job with a plurality of installation jobs.Type: GrantFiled: March 30, 2020Date of Patent: April 9, 2024Assignee: AT&T Intellectual Property I, L.P.Inventors: Vijayan Nagarajan, Abhay Dabholkar, Parth Sutaria

Patent number: 11902309Abstract: Historical time-series data can be analyzed using a probabilistic model to determine one or more distributions, including at least a normal distribution and an anomaly distribution. These distributions can be analyzed to obtain values for distribution parameters, such as mean, standard deviation, and density, as well as other statistical parameters, for use in building a forecasting model. This model can analyze the time-series data to predict or forecast actionable anomalies at one or more future points or periods in time, such as may exceed a determined anomaly threshold with at least a minimum amount of confidence. A determination can be made as to one or more actions to take in anticipation of the anomalous event, or volume of events, such as to attempt to prevent the occurrence or to be better positioned to handle the occurrence. Such forecasting or prediction can utilize both modeling and feature engineering.Type: GrantFiled: June 25, 2021Date of Patent: February 13, 2024Assignee: Amazon Technologies, Inc.Inventors: Vijayan Nagarajan, Lisa Harrington Waygood, Siddharth Krishnamurthy

Publication number: 20220318545Abstract: Techniques for processing of electronic documents comprising tables to desirably extract and/or recreate tables, including information in the tables, are presented. A document processing management component (DPMC) can perform a multi-stage process to extract a table from a document and recreate the table, including the table structure and information, in an editable form. During first stage, DPMC can identify candidate cells of the table based on analysis of the document, including identifying border lines that can represent cell borders, identifying any free floating candidate cells, and identifying characters of the candidate cells. During second stage, DPMC can determine structural relationships between respective candidate cells and respective neighbor candidate cells in all directions, based on applicable rules, and record the respective associations between those candidate cells.Type: ApplicationFiled: April 5, 2021Publication date: October 6, 2022Inventors: Tyler Poff, Vijayan Nagarajan, Abhay Dabholkar, Abhishek Mishra
