Publication number: 20230260281Abstract: A system described herein may provide a technique for using modeling techniques to identify events, trends, etc. in a set of data, such as streaming video or audio content. The system may perform lightweight pre-processing operations on a different set of data, such as object position data, to identify timeframes at which an event may potentially have occurred, and the modeling techniques may be performed at portions of the streaming content that correspond to such timeframes. The system may forgo performing such modeling techniques at other portions of the streaming content, thus conserving processing resources.Type: ApplicationFiled: February 16, 2022Publication date: August 17, 2023Applicant: Verizon Patent and Licensing Inc.Inventors: Le Su, Lin Tang, Krishna Pichumani Iyer, Yu Wan, Yiming Chen, Wenyuan Lu

Patent number: 11588833Abstract: A traceback solution is provided. For a network of autonomous systems, the traceback solution traces the autonomous system path taken by traffic flows. Every link in the traceback path is created, verified, and audited by autonomous systems. Multiple autonomous systems may take part in the process, making the system robust against fake information. The database used to store the validated traceback paths is a decentralized and distributed storage. Multiple copies of the database may be maintained by the network of autonomous systems. The database may be accessible by any participating autonomous system; and is not accessible from outside the network of autonomous systems. The traceback solution achieves both validation and non-repudiation property among the ASes. The traceback solution mitigates some important attack scenarios that might be targeted specifically at the traceback solution.Type: GrantFiled: December 26, 2017Date of Patent: February 21, 2023Assignee: Agency for Science, Technology and ResearchInventors: Le Su, Dinil Mon Divakaran, Vrizlynn Ling Ling Thing

Patent number: 10728773Abstract: A Self-Organizing Network (SON) collects data pertaining to a first number of cells of a wireless network. The SON splits the collected data into a second number of groups, and, for each of the second number of groups, repeatedly set a third number of clusters to a different number between a low limit and a high limit. The SON, for each of the settings, clusters the cells into the third number of clusters and trains a deep neural network to perform a regression analysis on the third number of clusters. For each of the second number of groups, the SON also determines an optimum number of clusters based on the regression analyses, re-clusters the cells into the optimum number of clusters; and tunes engineering parameters based on the re-clustering to optimize performance of the wireless network and quality of experience pertaining to the wireless network.Type: GrantFiled: January 26, 2018Date of Patent: July 28, 2020Assignee: Verizon Patent and Licensing Inc.Inventors: Ye Ouyang, Le Su, Krishna Pichumani Iyer, Christopher M.
