Patent number: 11822590Abstract: A system and method for automatically detecting misinformation is disclosed. The misinformation detection system is implemented using a cross-stitch based semi-supervised end-to-end neural attention model which is configured to leverage the large amount of unlabeled data that is available. In one embodiment, the model can at least partially generalize and identify emerging misinformation as it learns from an array of relevant external knowledge. Embodiments of the proposed system rely on heterogeneous information such as a social media post's text content, user details, and activity around the post, as well as external knowledge from the web, to identify whether the content includes misinformation. The results of the model are produced via an attention mechanism.Type: GrantFiled: October 14, 2021Date of Patent: November 21, 2023Assignee: Accenture Global Solutions LimitedInventors: Shubhashis Sengupta, Milind Savagaonkar, Nidhi, Tanmoy Chakraborty, William Scott Paka, Rachit Bansal

Patent number: 11823592Abstract: The disclosed system and method focus on automatically generating questions from input of written text and/or audio transcripts (e.g., learning materials) to aid in teaching people through testing their knowledge about information they have previously been presented with. These questions may be presented to an end user via a conversational system (e.g., virtual agent or chatbot). The user can iterate through each question, provide feedback for the question, attempt to answer the question, and/or get an answer score for each answer. The disclosed system and method can generate questions tailored to a particular subject by using teaching materials as input. The disclosed system and method can further curate the questions based on various conditions to ensure that the questions are automatically selected and arranged in an order that best suits the subject taught and the learner answering the questions.Type: GrantFiled: August 31, 2021Date of Patent: November 21, 2023Assignee: Accenture Global Solutions LimitedInventors: Roshni Ramesh Ramnani, Shubhashis Sengupta, Saurabh Agrawal

Publication number: 20230367669Abstract: Embodiments of the present disclosure provide systems, methods, and computer-readable storage media that leverage artificial intelligence and machine learning to identify, diagnose, and mitigate occurrences of network faults or incidents within a network. Historical network incidents may be used to generate a model that may be used to evaluate real-time occurring network incidents, such as to identify a cause of the network incident. Clustering algorithms may be used to identify portions of the model that share similarities with a network incident and then actions taken to resolve similar network incidents in the past may be identified and proposed as candidate actions that may be executed to resolve the cause of the network incident. Execution of the candidate actions may be performed under control of a user or automatically based on execution criteria and the configuration of the fault mitigation system.Type: ApplicationFiled: June 12, 2023Publication date: November 16, 2023Inventors: Sanjay Tiwari, Shantha Maheswari, Surya Kumar Ivg, Mathangi Sandilya, Gaurav Khanduri, Shubhashis Sengupta, Marcio Miranda Theme, Badarayan Panigrahi, Tarang Kumar

Publication number: 20230072171Abstract: A system and method for training and refining a machine learning model is disclosed. The disclosed system and method can further improve the accuracy of trained machine learning models by calculating which threshold values for predictions (e.g., probabilities output by the machine learning model) provide the most accurate results. The system and method may include applying an optimization technique (e.g., multi-objective optimization) to calculate which threshold values result in the best combination of precision and recall. In other words, the system and method adjust threshold values for prediction scores to optimize the objects of precision and recall. A machine learning model trained with these adjusted threshold values can determine when an input belongs to an unknown class because the unknown input has prediction scores below the threshold values for every known class. Embodiments may include refining an intent classifier to better classify unknown intents.Type: ApplicationFiled: June 10, 2022Publication date: March 9, 2023Inventors: Shubhashis Sengupta, Roshni Ramesh Ramnani, Sakshi Jain, Prerna Prem, Asif Ekbal, Zishan Ahmad

Patent number: 11416755Abstract: The present system and method may generally include organizing the task flow of a virtual agent in a way that is controlled by a set of rules and set of conditional probability distributions. The system and method may include receiving a user utterance including a first task, identifying the first task from the user utterance, and obtaining a set of rules related to the plurality of tasks. The set of rules may determine whether pre-tasks and/or pre-conditions are to be executed before executing the first task. The set of rules may also determine whether post-tasks and/or post-conditions are to be executed after executing the first task. The system and method may include executing the task; running a probabilistic graphical model on the plurality of tasks to determine a second task based on the first task; suggesting to the user the second task; and updating the probabilistic graphical model after a threshold number of runs.Type: GrantFiled: August 30, 2019Date of Patent: August 16, 2022Assignee: Accenture Global Solutions LimitedInventors: Roshni Ramesh Ramnani, Shubhashis Sengupta, Moushumi Mahato, Sukanti Beer

Patent number: 11397888Abstract: A virtual agent with a dialogue management system and a method of training the dialogue management system is disclosed. The dialogue management system is trained using a deep reinforcement learning process. Training involves obtaining or simulating training dialogue data. During the training process, actions for the dialogue management system are selected using a Deep Q Network to process observations. The Deep Q Network is updated using a target function that includes a reward. The reward may be generated by considering one or more of the following metrics: task completion percentage, dialogue length, sentiment analysis of the user's response, emotional analysis of the user's state, explicit user feedback, and assessed quality of the action. The set of actions that the dialogue management system can take at any time may be limited by an action screener that predicts the subset of actions that the agent should consider for a given state of the system.Type: GrantFiled: June 14, 2018Date of Patent: July 26, 2022Assignee: Accenture Global Solutions LimitedInventors: Harshawardhan Madhukar Wabgaonkar, Shubhashis Sengupta, Tulika Saha
