Publication number: 20190130406Abstract: Training risk determination models based on a set of labeled data transactions. A first set of labeled data transactions that have been labeled during a review process is accessed. A first risk determination model is trained using the first set of labeled data transactions. A first risk score for data transactions of a set of unlabeled data transactions is determined using the first risk determination model. Data transactions in the set of unlabeled data transactions are newly labeled based on the first risk score. The newly labeled data transactions are added to a second set of labeled data transactions that include the first set of labeled data transactions. A second risk determination model is trained using at least the second set of labeled data transactions. A second risk score is determined for subsequently received data transactions and these data transactions are rejected or approved based on the second risk score.Type: ApplicationFiled: November 2, 2017Publication date: May 2, 2019Inventors: Cezary A.

Publication number: 20190114639Abstract: Embodiments disclosed herein are related to computing systems and methods for detecting anomalies in a distribution of one or more attributes associated with data transactions. In the embodiments, data transactions are accessed that each include various attributes. The data transactions are grouped into a first subset associated with a first sub-type of a first attribute and a second subset including any remaining sub-types of the first attribute. Second attributes in the first and second subsets are compared to determine differences in the proportion of the second attributes between the first and second subsets, where the differences are indicative of an anomaly in an expected distribution of the second attributes. Based at least on a determination that there are differences in the proportion, subsequently accessed data transactions that are associated with attributes similar to the data transactions of the first subset are rejected or subjected to a further review process.Type: ApplicationFiled: October 16, 2017Publication date: April 18, 2019Inventors: Eric W. Nick, Ming-Yu Fan, Hung-Chih Yang, Shoou-Jiun Wang, Cezary A. Marcjan, Jayaram NM Nanduri

Patent number: 9734235Abstract: A canopy clustering process merges at least one set of multiple single-center canopies together into a merged multi-center canopy. Multi-center canopies, as well as the single-center canopies, can then be used to partition data objects in a dataset. The multi-center canopies allow a canopy assignment condition constraint to be relaxed without risk of leaving any data objects in a dataset outside of all canopies. Approximate distance calculations can be used as similarity metrics to define and merge canopies and to assign data objects to canopies. In one implementation, a distance between a data object and a canopy is represented as the minimum of the distances between the data object and each center of a canopy (whether merged or unmerged), and the distance between two canopies is represented as the minimum of the distances for each pairing of the center(s) in one canopy and the center(s) in the other canopy.Type: GrantFiled: October 18, 2014Date of Patent: August 15, 2017Assignee: Microsoft Technology Licensing, LLCInventors: Xiong Zhang, Danny Lange, Hung-Chih Yang

Publication number: 20160188604Abstract: A system for identifying influential users of a social network platform. The system may compute a score for each of multiple users. Such a score may be topic-based, leading to a more accurate identification of influential users. Such a topic-based score may indicate authority and/or impact of a user with respect to a topic. The impact may be computed based on authority combined with other factors, such as power of the user. The authority score may be simply computed, in whole or in part, directly from a tweet log without, for example creating a retweet graph. As a result, the scores may be computed, using MapReduce primitives or other constructs that allow the computations to be distributed across multiple parallel processors. Such scores may be used to select users based on impact as part of social trend analysis, marketing or other functions.Type: ApplicationFiled: March 3, 2016Publication date: June 30, 2016Applicant: Microsoft Technology Licensing, LLCInventors: Danny B.

Patent number: 9218630Abstract: Techniques for identifying influential users of a social networking service are provided. Influential users may be identified via an algorithm in which an influence score is assigned to each user based at least in part on other members of the community users having taken an affirmative step with respect to the user's communications. Iterative processing may be performed, with each user's influence score being determined by contributions from other users, and each contribution being determined by the contributor's influence score as of a prior iteration. A map-reduce framework may be employed, with data representing the community being partitioned into a plurality of discrete shards, a map process corresponding to each shard calculating an influence score for users represented in the shard, and reduce processes ranking users according to influence score across all shards.Type: GrantFiled: March 22, 2012Date of Patent: December 22, 2015Assignee: Microsoft Technology Licensing, LLCInventors: Hung-Chih Yang, Danny B.
