论文摘要
Precision Medicine根据患者的特征为患者提供定制的治疗方法,是提高治疗效率的有前途的方法。大规模的OMICS数据对于患者表征很有用,但是它们的测量经常会随着时间而变化,从而导致纵向数据。随机森林是用于构建预测模型的最先进的机器学习方法之一,并且可以在精密医学中发挥关键作用。在本文中,我们回顾了标准随机森林方法的扩展,以进行纵向数据分析。扩展方法根据其设计的数据结构进行分类。我们考虑单变量和多变量响应,并根据时间效应是否相关,进一步对重复测量进行分类。还提供了审核扩展程序的可用软件实现信息。我们在讨论我们的审查局限性和一些未来的研究方向的讨论中结束。
Precision medicine provides customized treatments to patients based on their characteristics and is a promising approach to improving treatment efficiency. Large scale omics data are useful for patient characterization, but often their measurements change over time, leading to longitudinal data. Random forest is one of the state-of-the-art machine learning methods for building prediction models, and can play a crucial role in precision medicine. In this paper, we review extensions of the standard random forest method for the purpose of longitudinal data analysis. Extension methods are categorized according to the data structures for which they are designed. We consider both univariate and multivariate responses and further categorize the repeated measurements according to whether the time effect is relevant. Information of available software implementations of the reviewed extensions is also given. We conclude with discussions on the limitations of our review and some future research directions.
