Publication number: 20240054803Abstract: Systems, methods, and other embodiments associated with identifying a document type of an unidentified document based on image features are described. In one embodiment, image pairs are formed by pairing the unidentified document with anchor images from a plurality of anchor images, wherein each anchor image is a known document type. For each image pair, first visual features are extracted from the unidentified document and second visual features are extracted from the paired anchor image. A similarity function is applied to compare the first visual features and the second visual features, and a similarity score is generated for each image pair based on the comparing. The most similar anchor image from the image pairs, which has a greatest similarity score, is identified. The document type of the unidentified document is then predicted as the known document type associated with the most similar anchor image.Type: ApplicationFiled: August 15, 2022Publication date: February 15, 2024Inventors: Shubham NEGI, Krishna Sameera ELLENDULA, Rahul YADAV, Veresh JAIN

Publication number: 20230419130Abstract: Systems, methods, and other embodiments associated with a data quality framework for a machine learning pipeline are described. In one embodiment, a method includes receiving an input dataset prior to training a machine learning model with the input dataset. The input dataset, having data records in column tabular form, is analyzed to determine a data quality of the input dataset prior to training the machine learning model. A data quality score is generated that represents an overall quality of the input dataset, where the data quality score is generated based on a combined ensemble of at least two factors selected from (i) an abundance factor, (ii) a completeness factor, and (iii) a dimension efficiency factor. Based on the data quality score, the input dataset is either permitted or prohibited from continuing in the machine learning pipeline, and corrective actions may be performed.Type: ApplicationFiled: June 28, 2022Publication date: December 28, 2023Inventors: Sharoon SAXENA, Veresh JAIN, Rahul YADAV

Publication number: 20230177602Abstract: According to an aspect, a technology system maintains an account data specifying the details of multiple accounts including a specific set of accounts as being delinquent. Upon receiving a feature set to be used, the system clusters the multiple accounts into groups based on the feature set. The system generates a multi-classification model for assignment of agents to the accounts based on the group qualifiers associated with the groups and the feature set. The system then identifies a target group likely to present problems with debt collection, assigns, using the multi-classification model, a corresponding agent for each account of the group and determines a recommended recovery strategy for each assignment. The system provides the details of the group, the corresponding agents assigned and the recommended recovery strategy for each assignment.Type: ApplicationFiled: April 13, 2022Publication date: June 8, 2023Inventors: Rahul Yadav, Veresh Jain, Shubham Negi, Rahul Kiran Gaddam, Phanindra Choda

Patent number: 9996402Abstract: NUMA-aware reader-writer locks may leverage lock cohorting techniques and may support reader re-entrancy. They may implement a delayed sleep mechanism by which a thread that fails to acquire a lock spins briefly, hoping the lock will be released soon, before blocking on the lock (sleeping). The maximum spin time may be based on the time needed to put a thread to sleep and wake it up. If a lock holder is not executing on a processor, an acquiring thread may go to sleep without first spinning. Threads put in a sleep state may be placed on a turnstile sleep queue associated with the lock. When a writer thread that holds the lock exits a critical section protected by the lock, it may wake all sleeping reader threads and one sleeping writer thread. Reader threads may increment and decrement node-local reader counters upon arrival and departure, respectively.Type: GrantFiled: April 7, 2014Date of Patent: June 12, 2018Assignee: Oracle International CorporationInventor: Rahul Yadav
