摘要
由于学习效率受到多种因素的影响,学习效率的评估变得复杂和困难,导致评估差较大.因此,文章提出基于改进主成分分析的高校专业课程学习效率评估方法.该方法首先爬取高校专业课程学习指标数据,利用改进主成分分析方法确定学习评估信息熵;其次,构建高校专业课程学习效率评估函数,得到高校专业课程学习效率综合评价得分;最后,应用模糊K-means聚类算法实现学习效率梯度评估.设计对比实验,实验结果证明了该方法能够准确反映学生的学习效率,在实际工作中有很高的应用价值.
Abstract
Due to the influence of various factors on learning efficiency,the evaluation of learning efficiency becomes complex and difficult,resulting in significant evaluation errors.Therefore,a method for evaluating the learning efficiency of university professional courses based on improved principal component analysis is proposed.Firstly,the proposed method crawls the learning index data of college professional courses,then uses improved principal component analysis method to determine the learning evaluation information entropy,constructs a learning efficiency evaluation function for university professional courses,obtains the comprehensive evaluation score of learning efficiency for college professional courses,and finally applies the fuzzy K-means clustering algorithm to achieve learning efficiency gradient evaluation.The comparative experiments are designed,and the experimental results demonstrate that this method can more accurately reflect the learning efficiency of students,which has high application value in practice.
