摘要

大学排名是一种衡量高等教育机构(HEIs)表现的技术,通过学生满意度、支出、研究和教学质量、引用次数、拨款和入学率等各种标准对其进行评估。排名被认为是帮助学生决定就读哪所院校的重要因素。因此,各大学都在努力提高自己的综合排名,在市场宣传中使用这些衡量成功的标准,并在学校网站的显著位置公布自己的排名情况。尽管对排名方法的研究已有数十年历史,但利用预测分析和机器学习对大学进行排名的研究数量有限。在本文中,我们收集了 49 所加拿大大学 2017-2021 年的数据,并根据麦克林的分类将其分为主要本科大学、综合大学和医科大学/博士生大学。在确定输入和输出成分后,我们利用各种特征工程和机器学习技术来预测大学的排名。结果表明,"师生比例"、"引用总数 "和 "资助总数 "是加拿大大学排名的最重要因素。此外,用于 "主要本科生类别 "的随机森林机器学习模型、用于 "综合类别 "的投票分类器模型和用于 "医学/博士类别 "的梯度提升模型表现最佳。根据准确率、精确度、F1 分数和召回率对所选的机器学习模型进行了评估。

A machine learning approach feature to forecast the future performance of the universities in Canada

University ranking is a technique of measuring the performance of Higher Education Institutions (HEIs) by evaluating them on various criteria like student satisfaction, expenditure, research and teaching quality, citation count, grants, and enrolment. Ranking has been determined as a vital factor that helps students decide which institution to attend. Hence, universities seek to increase their overall rank and use these measures of success in their marketing communications and prominently place their ranked status on their institution's websites. Despite decades of research on ranking methods, a limited number of studies have leveraged predictive analytics and machine learning to rank universities. In this article, we collected 49 Canadian universities’ data for 2017–2021 and divided them based on Maclean's categories into Primarily Undergraduate, Comprehensive, and Medical/Doctoral Universities. After identifying the input and output components, we leveraged various feature engineering and machine learning techniques to predict the universities’ ranks. We used Pearson Correlation, Feature Importance, and Chi-Square as the feature engineering methods, and the results show that “student to faculty ratio,” “total number of citations”, and “total number of Grants” are the most important factors in ranking Canadian universities. Also, the Random Forest machine learning model for the “primarily undergraduate category,” the Voting classifier model for the “comprehensive category” and the Gradient Boosting model for the “medical/doctoral category” performed the best. The selected machine learning models were evaluated based on accuracy, precision, F1 score, and recall.
