Example Embodiment

[0059] Example 1

[0060] First, according to its own actual situation, after data governance, the school establishes a cloud campus big data center to store student information data.

[0061] On the basis of the data center, students are asked to log in to the course selection system for the first time every semester to fill in the information when selecting courses, obtain the student information data through the educational administration system, extract the student feature data set X after data processing, and calculate the similar student set D of the students to be recommended. .

[0062] The sample data set consists of the students to be recommended E=(e 1 ,e 2 ,...,e 6 ,e 7 ) and the set of previous students C={x 1 ,x 2 ,x 3 ,...,x n}composition.

[0063] Selected features include:

[0064] Obtain the basic personal information of students in the educational administration system, extract the three characteristics of college, gender, and major, as well as the...
