Claim 0:
1. A method for providing information on a user's concept understanding, the method comprising the steps of:
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,
wherein the concept-specific understanding estimation model is trained such that the 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, on the basis of a weighting function as below:, w
    tl
   
   =
   
    
     
      d
      
       t
       -
       l
      
     
     
      
       
        ∑
         
       
       
        l
        =
        1

     (
     
      0
      ,
      1

where wtl denotes a weight assigned to a 1th piece of the sequence data out oft pieces of the sequence data, and d denotes a user-defined constant.
