Abstract

We introduce a pipeline for time series classification that extracts features based on the iterated-sums signature (ISS) and then applies a linear classifier. These features are intrinsically nonlinear, capture chronological information, and, under certain settings, are invariant to a form of time-warping. We achieve competitive results, both in accuracy and speed, on the UCR archive. We make our code available at https://github.com/irkri/fruits.

FRUITS：利用迭代和进行时间序列分类的特征提取

我们介绍了一种时间序列分类方法，它根据迭和特征（ISS）提取特征，然后应用线性分类器。这些特征本质上是非线性的，能捕捉时间信息，而且在某些设置下，不受某种形式的时间扭曲的影响。我们在 UCR 档案中取得了极具竞争力的准确性和速度。我们在 https://github.com/irkri/fruits 网站上提供了我们的代码。

期刊介绍： Advances in data gathering, storage, and distribution have created a need for computational tools and techniques to aid in data analysis. Data Mining and Knowledge Discovery in Databases (KDD) is a rapidly growing area of research and application that builds on techniques and theories from many fields, including statistics, databases, pattern recognition and learning, data visualization, uncertainty modelling, data warehousing and OLAP, optimization, and high performance computing.
