论文摘要
早期时间序列分类(ETSC)是通过观察尽可能少的测量值来预测传入时间序列类别的任务。可以使用此类方法在许多关键时期应用中获得分类预测。但是,可用技术并不适合每个问题,因为数据特征的差异可能会影响算法性能,从而在早期,准确性,F1得分和训练时间方面影响算法。我们在公开可用的数据以及两个源自生命科学和海事领域的新介绍的数据集上评估了六种现有的ETSC算法。我们的目标是为ETSC算法的评估和比较提供一个框架,并获得有关此类方法在现实生活应用中的执行方式的直觉。提出的框架也可以作为新技术的基准。
Early Time-Series Classification (ETSC) is the task of predicting the class of incoming time-series by observing as few measurements as possible. Such methods can be employed to obtain classification forecasts in many time-critical applications. However, available techniques are not equally suitable for every problem, since differentiations in the data characteristics can impact algorithm performance in terms of earliness, accuracy, F1-score, and training time. We evaluate six existing ETSC algorithms on publicly available data, as well as on two newly introduced datasets originating from the life sciences and maritime domains. Our goal is to provide a framework for the evaluation and comparison of ETSC algorithms and to obtain intuition on how such approaches perform on real-life applications. The presented framework may also serve as a benchmark for new related techniques.
