Embodiment Construction

[0063] The present invention is described in detail below in conjunction with accompanying drawing:

[0064] Such as figure 1 Shown, the student's academic achievement prediction method based on Naive Bayesian model of the present invention comprises the following major steps:

[0065] Step 1: Collect student data, including students' academic performance and learning behavior information;

[0066] Step 2: Convert and process the student data to obtain a standardized student learning status data table;

[0067] Step 3: Construct a student academic performance prediction model based on the naive Bayesian model from the standardized student learning status data table, and learn the parameters of the prediction model;

[0068] Step 4: According to the obtained model probability parameters, use the Naive Bayesian model to predict the student's academic achievement category.

[0069] The invention can predict the future academic performance of the students according to the stude...

Abstract

The invention discloses a student academic performance prediction method and a student academic performance prediction system based on a Naive Bayes model. The method comprises the steps of acquiring learning data of students, and transmitting the acquired data to a database of a first server; implementing data conversion on the learning data of the students stored in the database to acquire a standardized student learning condition data sheet; aiming at the standardized student learning condition data sheet, computing a conditional probability of each property in different classifications and prior probabilities of different classifications by a computation unit in the server; and implementing data conversion on the data of the student to be predicted and inputting the converted data to the trained Naive Bayes model to implement classification prediction on the student data. According to the method and system of the invention, the Naive Bayes model is adopted, and the model is used for accurately predicting the academic performance of the student, with high reliability.

Description

technical field [0001] The invention relates to the fields of educational technology and computer application subjects, in particular to a method and system for predicting students' academic performance based on a naive Bayesian model. Background technique [0002] At present, my country's higher education is developing rapidly, and the number of general institutions of higher learning has reached more than 2,500. In recent years, the continuous decline in the number of students has brought a huge survival crisis to ordinary colleges and universities. How to improve the quality of student training and the employment competitiveness of students has become a problem that many colleges and universities need to solve urgently. As an important core indicator of the quality of student training, students' academic performance has attracted much attention from university administrators. [0003] In my country's colleges and universities, the youth league committee counselor (head ...
