Publication number: 20240070456Abstract: Provided are systems and methods for corrective reward optimization for generative sequential labeling. In particular, example aspects of the present disclosure are directed to an effective framework for generative reward optimization of text (or other) data sequences, certain example implementations of which can be referred to as “GROOT”. Example implementations of the proposed framework work by training a generative sequential labeling model to match the decoder output distribution with that of the (possibly black-box) reward function. Using an iterative training regime, the framework can first generate prediction candidates and then correct errors in the candidate. Finally, a loss function can be used that contrasts those candidates based on their reward values (e.g., as measured by a reward function that encodes the specific objectives for a particular setting or application).Type: ApplicationFiled: August 31, 2023Publication date: February 29, 2024Inventors: Karthik Raman, Kazuma Hashimoto

Publication number: 20220335034Abstract: Data services for workloads are often provided with a service level agreement specifying various performance guarantees (e.g., latency, availability, scalability, and consistency). Single-master architectures, in which updates t the data set are constrained to a single server, may limit the fulfillment of some performance guarantees. Presented herein are multi-master architectures, in which the server set is partitioned into at least two masters are permitted to update the data set and at least one non-master that is not permitted to update the data set. Non-masters that receive a request to update the data set forward the request to a master server for application to the data set. A master that receives the request applies it to the data set and propagates the update to other master and non-master servers. Conflicting updates may be resolved through a variety of conflict resolution techniques, optionally designating one master server as a conflict resolution server.Type: ApplicationFiled: June 30, 2022Publication date: October 20, 2022Inventors: Karthik RAMAN, Momin Mahmoud AL-GHOSHIEN, Bhalakumaaran ERODE RANGANATHAN, Madhan GAJENDRAN, Ji HUANG, Atul KATIYAR, Mikhail Mikhailovich KOLTACHEV, Sujit Vattathil KURUVILLA, Digvijaysinh Govindbhai MAKWANA, Subramanyam PATTIPAKA, Ovidiu Constantin PLATON, Ankur Savailal SHAH, Pankaj SHARMA, Dharma SHUKLA, Shreshth SINGHAL, Shireesh Kumar THOTA

Patent number: 11397721Abstract: A server set for a data set may designate a subset of “master” servers that update the data set in order to reduce data version conflicts involving mutually exclusive updates of the data set. Multi-master configurations may fulfill the performance constraints, and the subset of masters may detect and resolve data version conflicts. However, if multiple masters perform conflict resolution for a particular data version conflict, the resolution may produce inefficiency and redundancy (if the masters reach the same outcome) or additional data version conflicts (if the masters reach different outcomes). Instead, among the masters, a merge master may be identified that applies conflict resolution techniques to data version conflicts and forwards the conflict resolution outcome to the other masters for application to the data set to resolve the data version conflict. The other masters may temporarily store updates in a tentative update set until data version conflicts are resolved.Type: GrantFiled: December 4, 2018Date of Patent: July 26, 2022Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Karthik Raman, Momin Mahmoud Al-Ghosien, Bhalakumaaran Erode Ranganathan, Madhan Gajendran, Ji Huang, Atul Katiyar, Mikhail Mikhailovich Koltachev, Sujit Vattathil Kuruvilla, Digvijaysinh Govindbhai Makwana, Subramanyam Pattipaka, Ovidiu Constantin Platon, Ankur Savailal Shah, Pankaj Sharma, Dharma Shukla, Shreshth Singhal, Shireesh Kumar Thota

Patent number: 11321303Abstract: Data services are often provided with various performance guarantees. Multi-master architectures, in which multiple master servers are permitted to update a portion of the data set, may facilitate some performance requirements, but may also lead to data version conflicts in which different masters have written different versions of one or more data items. Moreover, conflicts involving different data items may have to be resolved using different conflict resolution techniques. Therefore, various data items of the data set may be associated with a conflict resolution technique selected from a conflict resolution technique set, such as manual conflict resolution; a write order policy, such as last writer wins; a conflict resolution logic; and conflict resolution based on data types. A data version conflict may be resolved by identifying and invoking the selected conflict resolution technique that is associated with the data item, and applying the conflict resolution outcome to the data item.Type: GrantFiled: December 2, 2018Date of Patent: May 3, 2022Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Karthik Raman, Momin Mahmoud Al-Ghosien, Bhalakumaaran Erode Ranganathan, Madhan Gajendran, Ji Huang, Atul Katiyar, Mikhail Mikhailovich Koltachev, Sujit Vattathil Kuruvilla, Digvijaysinh Govindbhai Makwana, Subramanyam Pattipaka, Ovidiu Constantin Platon, Ankur Savailal Shah, Pankaj Sharma, Dharma Shukla, Shreshth Singhal, Shireesh Kumar Thota

Patent number: 11269679Abstract: Distributed transactions are performed over a collection of servers operating as replicas of a data set, where a successful transaction involves meeting a quorum count of replicas that locally commit the transaction. However, performance constraints of data sets and consuming applications may vary (e.g., sensitivity to latency, scalability, and/or consistency), and the performance characteristics of the server set may be partly determined by the transactional commitment and quorum selection. The distributed transaction may be applied by designating the replicas as a set of followers and a leader that initiates the transaction and receives acknowledgments of local commits by each follower. On condition of the acknowledgments meeting a quorum count for the data set according to the performance characteristics of the application, the leader locally commits the transaction and delivers a result.Type: GrantFiled: May 4, 2018Date of Patent: March 8, 2022Assignee: Microsoft Technology Licensing, LLCInventors: Karthik Raman, Arsalan Ahmad, Momin Mahmoud Al-Ghosien, Padma Priya Aradhyula Bhavani, Rajeev Sudhakar Bhopi, Junyan Guo, Ji Huang, Atul Katiyar, Hemant Kumar, Sujit Vattathil Kuruvilla, Ovidiu Constantin Platon, Venkata Sivaramakrishna Ramadugu, Ankur Savailal Shah, Pankaj Sharma, Dharma Shukla, Shreshth Singhal, Shireesh Kumar Thota

Patent number: 11144600Abstract: An application on a device may interact with a document service that provides access to a document service. The interaction may occur in a variety of contexts, such as a device context (e.g., the document service and the application provided on the same device), a local context (e.g., via a LAN), and a remote context (e.g., over the Internet). It may be advantageous to adapt the interaction to the current context, while also providing a consistent application interface that alleviates the application from context-specific implementations, and also achieving this adaptation in a performant manner. These considerations may be achieved in a balanced manner by providing a set of runtimes, where each runtime mediates the application/document service interaction between the application and the document service in a contextually adapted manner. The device may automatically detect the context of the interaction and select a contextually suitable runtime to service the application.Type: GrantFiled: September 10, 2019Date of Patent: October 12, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Dharma Shukla, Karthik Raman

Patent number: 11030185Abstract: Data sets such as databases are often distributed over a number of servers, where each server stores a subset of records and an index that enables the server to locate the records in response to queries. However, tight coupling of indexing and storage may limit load-balancing, fault recovery, and distribution. Instead, the set of servers may be partitioned into a set of storage servers that store the records and a set of index servers of the index over the records. In a set that is decoupled in this manner, load-balancing may involve provisioning and locating index servers independently of the provisioning and locating of the storage servers in view of the particular sensitivities and tolerances of various applications. Additionally, the index servers may also utilize a data layout that is selected and adapted independent of the data layout of the storage servers and/or the schema of the data stored thereby.Type: GrantFiled: May 29, 2018Date of Patent: June 8, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Karthik Raman, Momin Mahmoud Al-Ghosien, Samer Boshra, Brandon Chong, Madhan Gajendran, Mikhail Mikhailovich Koltachev, Aravind Ramachandran Krishna, Emily Lawton, Liang Li, Karan Vishwanath Popali, Adrian Ilcu Predescu, Ankur Savailal Shah, Pankaj Sharma, Dharma Shukla, Hari Sudan Sundar, Krishnan Sundaram, Shireesh Kumar Thota

Patent number: 10977573Abstract: Systems and methods provide distantly supervised wrapper induction for semi-structured documents, including automatically generating and annotating training documents for the wrapper. Training of the wrapper may occur in two phases using the training documents. An example method includes identifying a training set of semi-structured web pages having a subject entity that exists in a knowledge base and, for each training page, identifying target objects, identifying predicates in the knowledge base that connect the subject entity to a target objects identified in the training page, and annotating the training page. Annotating a training page includes generating a feature set for a mention of the target object, generating predicate-target object pairs for the mention, and labeling each predicate-target object pair with a corresponding example type and weight. The annotated training pages are used to train the wrapper to extract new subject entities and new facts from the set of semi-structured web pages.Type: GrantFiled: April 15, 2016Date of Patent: April 13, 2021Assignee: Google LLCInventors: Jeffrey Dalton, Karthik Raman, Evgeniy Gabrilovich, Kevin Patrick Murphy, Wei Zhang

Patent number: 10970270Abstract: Databases are often provided according to various organizational models (e.g., document-oriented storage, key/value stores, and relational database), and are accessed through various access models (e.g., SQL, XPath, and schemaless queries). As data is shared across sources and applications, the dependency of a data service upon a particular organizational and/or access models may become confining. Instead, data services may store data in a base representation format, such as an atom-record-sequence model. New data received in a native item format may be converted into the base representation format for storage, and converted into a requested format to fulfill data requests. Queries may be translated from a native query format into a base query format that is applicable to the base representation format of the data set, e.g., via translation into an query intermediate language (such as JavaScript) and compilation into opcodes that are executed by a virtual machine within the database engine.Type: GrantFiled: May 29, 2018Date of Patent: April 6, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Karthik Raman, Momin Mahmoud Al-Ghosien, Samer Boshra, Brandon Chong, Madhan Gajendran, Mikhail Mikhailovich Koltachev, Orestis Kostakis, Aravind Ramachandran Krishna, Liang Li, Jayanta Mondal, Balachandar Perumalswamy, Karan Vishwanath Popali, Adrian Ilcu Predescu, Vivek Ravindran, Ankur Savailal Shah, Pankaj Sharma, Dharma Shukla, Ashwini Singh, Vinod Sridharan, Hari Sudan Sundar, Krishnan Sundaram, Shireesh Kumar Thota, Oliver Drew Leonard Towers, Siddhesh Dilip Vethe
