摘要:

多器官衰竭(MOF)是一种危及生命的疾病。由于其紧迫性和高死亡率,早期发现对于临床医生提供适当的治疗至关重要。在本文中,我们进行定量分析的早期MOF预测与全面的机器学习(ML)配置,包括数据预处理(缺失值处理,标签平衡,功能缩放),特征选择,分类器的选择,和超参数调整。结果表明,分类器的选择影响的性能改善和变化的所有配置中。通常,包括集成方法的复杂分类器可以提供比简单分类器更好的性能。然而,盲目追求复杂的分类器是不明智的,因为它也带来了更大的性能变化的风险。

英文摘要:

Multiple organ failure (MOF) is a life-threatening condition. Due to its urgency and high mortality rate, early detection is critical for clinicians to provide appropriate treatment. In this paper, we perform quantitative analysis on early MOF prediction with comprehensive machine learning (ML) configurations, including data preprocessing (missing value treatment, label balancing, feature scaling), feature selection, classifier choice, and hyperparameter tuning. Results show that classifier choice impacts both the performance improvement and variation most among all the configurations. In general, complex classifiers including ensemble methods can provide better performance than simple classifiers. However, blindly pursuing complex classifiers is unwise as it also brings the risk of greater performance variation.
