Publication number: 20240136063Abstract: Systems and methods for out-of-distribution detection of nodes in a graph includes collecting evidence to quantify predictive uncertainty of diverse labels of nodes in a graph of nodes and edges using positive evidence from labels of training nodes of a multi-label evidential graph neural network. Multi-label opinions are generated including belief and disbelief for the diverse labels. The opinions are combined into a joint belief by employing a comultiplication operation of binomial opinions. The joint belief is classified to detect out-of-distribution nodes of the graph. A corrective action is performed responsive to a detection of an out-of-distribution node. The systems and methods can employ evidential deep learning.Type: ApplicationFiled: October 5, 2023Publication date: April 25, 2024Inventors: Xujiang Zhao, Haifeng Chen

Patent number: 11792167Abstract: Techniques for a flexible data security and machine learning system for merging third-party data are provided. In one technique, the system receives a data set from a third-party entity and receives selection data that indicates that the third-party entity selected a set of data security policies that includes an encryption option and a data mixing option from among multiple data mixing options. In response to receiving the selection data, the system stores data that associates the set of data security policies with the data set, encrypts the data set according to the encryption option, and persistently stores the encrypted data set. Later, the system decrypts the encrypted data set in volatile memory, generates, based on the data mixing option, training data based on the decrypted version of the data set, trains a machine-learned model based on the training data, and stores the machine-learned model in association with the data set.Type: GrantFiled: March 31, 2021Date of Patent: October 17, 2023Assignee: Microsoft Technology Licensing, LLCInventors: Haifeng Zhao, Yang Chen, Jiashuo Wang, Xiaojing Chen, Chencheng Wu, Souvik Ghosh, Ankit Gupta, Jing Wang, John Patrick Moore, Henry Heyburn Pistell, Mira Thambireddy, Haowen Cao, Keyi Yu

Publication number: 20220398488Abstract: Machine-learned model scoring techniques for reducing model invocations are provided. In one technique, first values for non-pair-specific interaction features that are associated with a first entity are identified. Second values for pair-specific interaction features that are associated with (a) the first entity and (b) a second entity that is different than the first entity are identified. A machine-learned model that has been trained based on the non-pair-specific interaction features and the pair-specific interaction features generates a first score based on the first values. The machine-learned model also generates a second score based on the first values and the second values. A final score for the first entity-second entity pair is computed based on the first score and the second score. Based on the final score, data about the first entity is transmitted over a computer network to a computing device associated with the second entity.Type: ApplicationFiled: June 11, 2021Publication date: December 15, 2022Inventors: Zhenjie ZHANG, Sanjay Reddy SATTI, Santhosh Kumar KUCHOOR, Wesley Kevin SUN, Guanyu WANG, Sai MADHAVAN, Michelle Seeton GALEMMO, Haifeng ZHAO

Patent number: 11080272Abstract: Entity resolution techniques for matching entity records from different data sources are provided. In one technique, an entity record from a source database is identified along with multiple data items included therein. Each data item corresponds to an attribute of multiple source attributes. For one of the data items that corresponds to a first source attribute, multiple target attributes are identified. A first query is generated that includes the data items and associates the data item with each of the multiple target attributes. A second query that is different than the first query is also generated. Two searches are performed of a target database: one based on the first query and the other based on the second query. A scoring model generates multiple scores, one for each search result. It is determined whether the entity record matches an entity record in the target database based on the set of scores.Type: GrantFiled: June 28, 2019Date of Patent: August 3, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Yang Chen, Liang Zhang, Haifeng Zhao, Jiashuo Wang, Aparna Krishnan, Anand Kishore, Chencheng Wu, John P.
