Patent number: 10387788Abstract: Techniques are provided for determining predicted results for entities based on relatedness of the entities in a graph of nodes. In an embodiment, the graph of nodes is generated based on the determined relatedness of the entities. A node in the graph of nodes represents an entity, and nodes representing entities with known results are assigned those results as their respective node values. The assigned node values are then propagated between the neighboring nodes throughout the graph of nodes in the amount determined by the relatedness of the nodes. Based on the propagation, node values for entities with unknown results are determined and represent the predicted results for those entities. Additionally, various classifiers may be combined with the propagated node values to increase the accuracy of the predicted results.Type: GrantFiled: February 18, 2016Date of Patent: August 20, 2019Assignee: LinkedIn CorporationInventors: Qiang Zhu, John Chao, Qingbo Hu

USING MACHINE LEARNING TECHNIQUES TO DETERMINE PROPENSITIES OF ENTITIES IDENTIFIED IN A SOCIAL GRAPH
Publication number: 20170308806Abstract: Techniques are provided for determining a propensity or likelihood that a person in a social network will perform a particular action. A statistical model that is trained based on multiple features of each member in a first plurality of members of a social network is stored. The multiple features include a subset pertaining to profile information provided by the first plurality of members and stored in a plurality of profiles of the first plurality of members. For each member of a second plurality of members of the social network, multiple feature values that correspond to the plurality of features are identified, the statistical model is used to generate a score for the member. The score indicates a likelihood that the member will perform the particular action.Type: ApplicationFiled: April 21, 2016Publication date: October 26, 2017Inventors: John Chao, Huan Hoang, Yan Liu, Qiang Zhu, Wenjing Zhang, Clay Blanchard, Christopher Fuller, Xing Zhou -
Publication number: 20170308913Abstract: Techniques are provided for displaying information about entities in a social network. An analysis of profiles of multiple representatives is performed. Each representative is registered with a social network provider and represents an organization from multiple organizations. Based on the analysis, the organizations are ranked. Data about a subset of the organizations is presented, based on the ranking, through a user interface. A user selects an indicator that is associated with a particular organization of the multiple organizations. In response to the input, a subset of the representatives is identified. One or more scores that were generated for a particular representative in the subset are determined. Data about the subset of the representatives is caused to be presented through the user interface. The data identifies the one or more scores and associates the one or more scores with the particular representative.Type: ApplicationFiled: April 21, 2016Publication date: October 26, 2017Inventors: John Chao, Derek Koh, Paul Ko, Lindsey Bly, Wenjing Zhang, Clay Blanchard, Carson Moore, Michael Derezin

Publication number: 20160353256Abstract: Techniques are provided for assigning members of a group to multiple target entities. A social proximity score is generated that reflects a measure of social relatedness between a group member and a target entity. Generated social proximity scores and one or more constraints are specified or referenced by a program. The program seeks to maximize social proximity scores in light of the one or more constraints. A solver executes the program to generate a result that assigns each target entity to at least one (or no more than one) group member.Type: ApplicationFiled: May 27, 2015Publication date: December 1, 2016Inventors: John Chao, Liangjie Hue, Huan Hoang, Wenjing Zhang, Michael Miller, Josh VanGeest, Qiang Zhu

Patent number: 8382692Abstract: A spine and neck support device adapted to support the anatomical structures in the cervical and upper thoracic spine when the user's neck is in flexion. A cushion conforms about the user's anatomical neck structures and rests on the upper chest of the user. The cushion has a chin support area that avoids contacting the user's chin when the user's head is in a neutral position and contacts the user's chin when the user's neck is in flexion. When the user's neck is flexed and the user's chin contacts the chin support area, the cushion unloads and supports the user's neck. At least one and preferably two straps are attached to the cushion and secure it to the user. The top is sloped downwards from back to front to maximize the user's downward field of vision. A groove in the posterior surface of the cushion accommodates the user's trachea/esophagus.Type: GrantFiled: June 10, 2010Date of Patent: February 26, 2013Inventor: John Chao

Patent number: 7907595Abstract: Customer Edge (CE) network elements can automatically learn IPSec tunnel endpoints for other CEs connected to sites in a Virtual Private Network (VPN) so that manual configuration of IPSec tunnel endpoints is not required and so that a centralized database of IPSec tunnel endpoints is not required to be separately maintained. According to an embodiment of the invention, a BGP export route policy is set on all CEs, so that when they announce their VPN routes in the standard format, the application of this export route policy changes the announcement to replace the BGP peering point address that would ordinarily be advertised with the IPSec tunnel endpoint address. When any given site receives a VPN route update formatted in this manner, it processes the VPN route update and learns from the update the IPSec tunnel endpoint as well as the associated VPN routes.Type: GrantFiled: September 29, 2006Date of Patent: March 15, 2011Assignee: Avaya, Inc.Inventors: Bakul Khanna, John Chao, Ramasamy Jesuraj, Robert Lee
