数据挖掘技术在学生成绩分析中的应用研究

The Application Researeh on Date Mining Technology in the Analysis of Students Scores

通过对传统决策树算法的介绍,阐述了改进后的C4.5算法将在挖掘时间上用时更少.通过对学生成绩进行预处理后,利用改进后的算法挖掘学生成绩之间的关联规则,分析并解释关联规则的结果.

Based on the introduction of the traditional decision tree algorithm, the improred algorithm is explained, which can reoluce the time of mining. After the pretreat ment of the studets＇scores, the improved algorithm is used to mine the association rules among the students＂ scores, and the results of the association rules are analyzed and solved.
