Publication number: 20220383100Abstract: A first neural network can be trained to approximate a state-action value function to estimate an expected cumulative return for an agent to perform an action in a given state, the agent being an autonomous reinforcement learning agent running on the processor. A second neural network can be trained to generate a simulated experience, the second network trained to predict a simulated state at a next time step after performing a given action, the second neural network being trained using real experience in a real environment. The first neural network is trained based on the simulated experience and a real experience from a real environment. A selected action selected by the second neural network given a current state of the real environment can be performed. The agent can explore an action space by uniformly sampling an action from all possible remaining action-state space combinations and performing the sampled action.Type: ApplicationFiled: June 1, 2021Publication date: December 1, 2022Inventors: Yada Zhu, Miao Liu, Alexander Gray, Nitin Gaur, Prasenjit Dey

Patent number: 11158203Abstract: A combination of knowledge representation and retrieval, assessments and personalization for a tutoring platform that provides an automated phased word exposition method for vocabulary learning and enable learners to learn words (or any learning objective) with sufficient proficiency and without excessive repetition. The phased learning objective method implements a moving average model that models the learner across multiple dimensions (e.g. reading, listening, writing, speaking) such that the platform is confident of the learner's understanding, while using minimal assessment doses, and such that the understanding transfers across experiences. The method implemented provides for multiple learning and assessment activities for a learning objective and leverages the same learner model for each learning dimension. Each word of a word set passes through learning and assessment-only phases for statistically significant evidence of learning.Type: GrantFiled: February 14, 2018Date of Patent: October 26, 2021Assignees: International Business Machines Corporation, Sesame WorkshopInventors: Ravi Kokku, Tamer E.

Patent number: 10930169Abstract: A system for performing implicit assessment of a pupil is provided. The system receives a learning content from a content provider, the learning content having checkpoints at different stages of the learning content. The system associates assessment instructions with each checkpoint of the learning content. The system renders the received learning content for presentation to a pupil and captures the behaviors of the pupil during the presentation of the learning content. The system performs an assessment of the pupil at each checkpoint encountered during the rendering of the learning presentation. The assessment at a checkpoint includes using the checkpoint's associated assessment instructions to assign a score based on the captured behaviors. The system then produces an overall evaluation based on the assessments performed at the encountered checkpoints.Type: GrantFiled: May 4, 2017Date of Patent: February 23, 2021Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Prasenjit Dey, Vijay Ekambaram, Ravindranath Kokku, Nitendra Rajput, Ruhi Sharma Mittal
