Patent number: 11587647Abstract: Techniques for candidate evaluation and filtering are provided. Enrollment criteria for a clinical trial are received, where the enrollment criteria include a plurality of conditions. A plurality of cost vectors is constructed for the plurality of conditions. A set of values for one or more of the plurality of conditions is determined for a candidate, where the set of values does not include a value for at least a first condition of the plurality of conditions. A utilized cost is generated for the candidate, based on the first set of values and the plurality of cost vectors. The candidate is then ranked based on the utilized cost.Type: GrantFiled: August 16, 2019Date of Patent: February 21, 2023Assignee: International Business Machines CorporationInventors: Bibo Hao, Shouyu Yan, Eryu Xia, Shi Lei Zhang

Patent number: 11281721Abstract: Techniques for augmenting relational databases with graph database capabilities are described. A graph database query requesting data from a graph database is received. The graph database includes a plurality of vertices and a plurality of edges. The graph database query is translated into a relational database query using one or more computer processors. The relational database query references a vertex table and an edge table in a relational database. Result data corresponding with the graph database query is retrieved from the relational database by executing the relational database query against the relational database.Type: GrantFiled: November 22, 2019Date of Patent: March 22, 2022Assignee: International Business Machines CorporationInventors: Sui Jun Tong, Wen Sun, Yi Qin Yu, Eryu Xia, Yong Qin

Patent number: 11120014Abstract: A computer-implemented method, system, and computer program product are provided for enhanced search strategies. The method includes selecting, by a processor device, known candidate sources related to a search topic. The method also includes ranking, by the processor device, keyphrase candidates from the known candidate sources according to inter-topic weighting. The method additionally includes assembling, by the processor device, a search string of a predetermined number of top ranked keyphrase candidates. The method further includes generating, by the processor device, new candidate sources from a candidate source repository responsive to the search string. The method also includes defining, by the processor device, a candidate source pool by the known candidate sources and the new candidate sources to reduce user search times on computer interface devices.Type: GrantFiled: November 23, 2018Date of Patent: September 14, 2021Assignee: International Business Machines CorporationInventors: Yi Qin Yu, En Liang Xu, Shi Lei Zhang, Bibo Hao, Eryu Xia

Patent number: 11045255Abstract: Patient treatment may be optimized using Recurrent Neural Network (RNN) based state simulation and Reinforcement learning (RL) techniques to simulate future states and actions. A RNN state simulator and a RL action generator may be trained using patient data such as historical states and actions. The RL action generator may be optimized by applying the RNN state simulator to simulating future states and applying the RL action generator to generate recommended actions based on the simulated future states. This process may be iteratively performed until a computational convergence is reached by the RL action generator which may indicate that the RL action generator has been optimized. A patient state may be fed into the optimized RL action generator to generate an optimal recommended treatment action.Type: GrantFiled: November 21, 2017Date of Patent: June 29, 2021Assignee: International Business Machines CorporationInventors: Jing Mei, Shi Wan Zhao, Gang Hu, Jing Li, Eryu Xia, En Liang Xu
