数据采掘:一种使用分类的性能改进预测

Data Mining: A prediction for performance improvement using classification

Brijesh Kumar Bhardwaj, Saurabh Pal

摘要:

目前教育数据库中存储的数据量迅速增加。这些数据库包含隐藏的信息,以提高学生的表现。印度高等教育的表现是所有学生学业的转折点。学生的学习成绩受多种因素的影响,因此有必要建立学生学习成绩的预测数据采掘模型,以识别高学习者和低学习者之间的差异。在本研究中,采用实验方法来生成数据库。在填补缺失值、将一种形式的值转换为另一种形式以及相关属性/变量选择方面对原始数据进行预处理。结果,我们有300名学生的记录,这是用于Byes分类预测模型的构建。关键词-数据采掘,教育数据采掘,预测模型,分类。

英文摘要:

Now-a-days the amount of data stored in educational database increasing rapidly. These databases contain hidden information for improvement of students' performance. The performance in higher education in India is a turning point in the academics for all students. This academic performance is influenced by many factors, therefore it is essential to develop predictive data mining model for students' performance so as to identify the difference between high learners and slow learners student. In the present investigation, an experimental methodology was adopted to generate a database. The raw data was preprocessed in terms of filling up missing values, transforming values in one form into another and relevant attribute/ variable selection. As a result, we had 300 student records, which were used for by Byes classification prediction model construction. Keywords- Data Mining, Educational Data Mining, Predictive Model, Classification.
