  • Patent number: 11676503
    Abstract: Systems and methods are provided by which a machine learning model may be executed to determine the probability that a given user will respond correctly to a given assessment item of a digital assessment on their first attempt. The machine learning model may process feature data corresponding to the user and the assessment item in order to determine the probability. The feature data may be calculated periodically and/or in real time or near-real time according to a machine learning model definition based on assessment data corresponding to the user's activity and/or based on responses submitted by all users to the assessment item and/or to content related to the assessment item.
    Type: Grant
    Filed: February 10, 2020
    Date of Patent: June 13, 2023
    Assignee: PEARSON EDUCATION, INC.
    Inventors: Mark E. Liedtke, Sumona J. Routh, Clayton Tong, Daniel L. Ensign, Victoria Kortan, Srirama Kolla
  • Patent number: 11443647
    Abstract: Systems and methods are provided by which an adaptive learning engine may be executed to determine the probability that a given user will respond correctly to a given assessment item of a digital assessment on their first attempt. The adaptive learning engine may apply one or more machine learning models to feature data corresponding to the user and the assessment item in order to determine the probability. The feature data may be calculated periodically and/or in real time or near-real time according to a machine learning model definition based on assessment data corresponding to the user's activity and/or based on responses submitted globally by users to the assessment item and/or to content related to the assessment item. Based on the correct first attempt probability, the adaptive learning engine may identify and recommend assessment items for which a user should be preemptively assigned credit.

  • Publication number: 20200258412
    Abstract: Systems and methods are provided by which an adaptive learning engine may select a machine learning model service to determine a probability that a user will respond correctly to a given assessment item of a digital assessment on their first attempt. The adaptive learning engine may receive a request identifying the user, the assessment item, and request data. A model selector may generate a model reference corresponding to a model definition based on the request data. The feature data to be retrieved and/or calculated may be defined by the model definition. The feature data may be processed by a model service executing a machine learning model selected by the adaptive learning engine based on the model definition. Based on the probability output by the model, the adaptive learning engine may whether the user should be preemptively assigned credit for the assessment item.
