  • Publication number: 20240096230
    Abstract: A method for providing information on a user's concept understanding is provided. The method includes acquiring a set of data on a user's understanding of concepts including a first concept estimated using a concept-specific understanding estimation model that is trained on the basis of concept-specific correctness/incorrectness sequence data, estimating the user's understanding of a second concept not encountered by the user using a matrix factorization algorithm on the concept-specific correctness/incorrectness sequence data represented in a matrix structure with respect to the first concept and the second concept, and visualizing the user's understanding of the first concept included in the acquired data set and the second concept on a device of the user. The concept-specific understanding estimation model is trained such that the concept understanding is estimated by assigning a greater weight to a piece of the concept-specific correctness/incorrectness sequence data generated at a later time point.
