摘要:

时间序列的早期分类已被广泛研究,以最大限度地减少医疗保健和金融等对时间敏感的应用中的类预测延迟。早期分类方法的一个主要任务是尽可能快地对不完整的时间序列进行分类,并具有一定的准确度。近年来,出现了几种时间序列的早期分类方法。由于大多数方法都从不同方面解决了早期分类问题,因此对现有解决方案进行全面审查以了解该领域的现状变得非常重要。这些解决方案已经证明了合理的性能,在广泛的应用,包括人类活动识别,基因表达为基础的健康诊断,工业monitoring,等在本文中,我们提出了一个系统的回顾,目前的文献早期分类方法为单变量和多变量的时间序列。我们将各种现有的方法分为四个专属类别的基础上,他们提出的解决方案的战略。这四类方法包括基于前缀的方法、基于shapelet的方法、基于模型的方法和其他方法。作者还讨论了早期分类在许多领域的应用,包括工业监测,智能交通和医疗。最后,我们对当前文献进行了快速总结,并指出了未来的研究方向。

英文摘要:

Early classification of time series has been extensively studied for minimizing class prediction delay in time-sensitive applications such as healthcare and finance. A primary task of an early classification approach is to classify an incomplete time series as soon as possible with some desired level of accuracy. Recent years have witnessed several approaches for early classification of time series. As most of the approaches have solved the early classification problem with different aspects, it becomes very important to make a thorough review of the existing solutions to know the current status of the area. These solutions have demonstrated reasonable performance in a wide range of applications including human activity recognition, gene expression based health diagnostic, industrial monitoring, and so on. In this paper, we present a systematic review of current literature on early classification approaches for both univariate and multivariate time series. We divide various existing approaches into four exclusive categories based on their proposed solution strategies. The four categories include prefix based, shapelet based, model based, and miscellaneous approaches. The authors also discuss the applications of early classification in many areas including industrial monitoring, intelligent transportation, and medical. Finally, we provide a quick summary of the current literature with future research directions.
