论文摘要

基于机器学习的方法在许多领域都变得越来越流行,因为它们允许以高DATA驱动的方式拟合模型,并且与经典方法相比,经常表现出可比性甚至增加的性能。但是,在教育科学领域,机器学习的应用仍然很少见。这项工作调查了使用分类树来分析教育科学数据的好处。在教育科学的背景下,对奥地利学校过渡率的数据的应用指示:(i)树木选择以数据驱动的方式预测学校过渡速率的变量,这些变量与教育科学的现有确认理论相符,(II)可以用来对回归模型进行可变量的选择,(ii)与模型进行分类的型号。这些结果表明,树木和其他机器学习方法也可能有助于探索高维教育数据集,尤其是在尚未开发验证理论的情况下。

Methods based on machine learning become increasingly popular in many areas as they allow models to be fitted in a highly-data driven fashion, and often show comparable or even increased performance in comparison to classical methods. However, in the area of educational sciences the application of machine learning is still quite uncommon. This work investigates the benefit of using classification trees for analyzing data from educational sciences. An application to data on school transition rates in Austria indicates different aspects of interest in the context of educational sciences: (i) the trees select variables for predicting school transition rates in a data-driven fashion which are well in accordance with existing confirmatory theories from educational sciences, (ii) trees can be employed for performing variable selection for regression models, (iii) the classification performance of trees is comparable to that of binary regression models. These results indicate that trees and possibly other machine learning methods may also be helpful to explore high-dimensional educational data sets, especially where no confirmatory theories have been developed yet.
