Jie Lu, Anjin Liu, Fan Dong, Feng Gu, Joao Gama, Guangquan Zhang

摘要:

概念漂移描述了流数据的底层分布随时间的不可预见的变化。概念漂移研究涉及漂移检测、理解和适应的方法和技术的发展。数据分析表明,如果不解决概念漂移问题,那么概念漂移环境中的机器学习将导致较差的学习结果。为了帮助研究人员确定哪些研究主题是重要的,以及如何在数据分析任务中应用相关技术,有必要对概念漂移领域的当前研究进展和趋势进行高质量,有指导意义的回顾。此外,由于近年来概念漂移的快速发展,概念漂移下的学习方法已经变得非常系统,揭示了一个在文献中没有提到的框架。本文回顾了130多篇概念漂移相关研究的文献,分析了概念漂移研究方法和技术的最新进展,建立了概念漂移下的学习框架,包括概念漂移检测、概念漂移理解和概念漂移适应三个主要部分。本文列出并讨论了10个流行的合成数据集和14个公开可用的基准数据集,用于评估针对处理概念漂移的学习算法的性能。此外,概念漂移相关的研究方向涵盖和讨论。通过提供最先进的知识,这项调查将直接支持研究人员在他们的理解在概念漂移下的学习领域的研究进展。

英文摘要:

Concept drift describes unforeseeable changes in the underlying distribution of streaming data over time. Concept drift research involves the development of methodologies and techniques for drift detection, understanding and adaptation. Data analysis has revealed that machine learning in a concept drift environment will result in poor learning results if the drift is not addressed. To help researchers identify which research topics are significant and how to apply related techniques in data analysis tasks, it is necessary that a high quality, instructive review of current research developments and trends in the concept drift field is conducted. In addition, due to the rapid development of concept drift in recent years, the methodologies of learning under concept drift have become noticeably systematic, unveiling a framework which has not been mentioned in literature. This paper reviews over 130 high quality publications in concept drift related research areas, analyzes up-to-date developments in methodologies and techniques, and establishes a framework of learning under concept drift including three main components: concept drift detection, concept drift understanding, and concept drift adaptation. This paper lists and discusses 10 popular synthetic datasets and 14 publicly available benchmark datasets used for evaluating the performance of learning algorithms aiming at handling concept drift. Also, concept drift related research directions are covered and discussed. By providing state-of-the-art knowledge, this survey will directly support researchers in their understanding of research developments in the field of learning under concept drift.
