Based on th..."Intemet+ education" has become a hot issue in the field of education in the past two years. "SPSS soRware application" teaching reform in the "Interact +" background, what will be the difference? Based on the overall goal of cultivating talents with innovative entrepreneurial ability, this paper mainly focuses on the "SPSS software application" course content and assessment methods. This study argues that although these ideas are yet to be verified, the teaching reform of this course must be innovative guidance value.展开更多
决策树模型是一种有监督的机器学习方法,分类规则通常采取IF-THEN形式,分析结果常以树形图呈现,具有可解释性强、易于理解的优势,在灾害预测、环境监测、临床诊疗决策等领域均有广泛的应用。本文从决策树模型概念入手,介绍了决策树模型...决策树模型是一种有监督的机器学习方法,分类规则通常采取IF-THEN形式,分析结果常以树形图呈现,具有可解释性强、易于理解的优势,在灾害预测、环境监测、临床诊疗决策等领域均有广泛的应用。本文从决策树模型概念入手,介绍了决策树模型的一般构建步骤、分类与回归树(classification and regression tree,CART)决策树模型在临床研究数据分析中的应用,并应用SPSS软件示例CART决策树模型的构建过程和实现方法,以期为临床研究者采用决策树模型进行数据分析提供参考。展开更多
