[0042] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0043] The present invention provides a student's personalized time interval perception attention mechanism knowledge tracking method, such as figure 1 shown, including the following steps:
[0044] (1) Collect and organize the historical interactive learning data and the corresponding time series in the process of students' problem-solving, and design and realize the students' personalized time interval relationship matrix. The specific implementation process is as follows:
[0045] (1.1) Student s∈S, S is the student set of the learning system, exercise e∈E, E is the exercise set of the student system, the learning sequence of student s is expressed as s={χ 1 ,χ 2 ,…χ n}={(e 0 ,a 0 ),(e 1 ,a 1 ),…(e n ,a n )}, χ t =(e t ,at ) indicates whether student s answered exercise e correctly at time t t , a t ∈{0,1}, the learning sequence s is transfor...
