Complexity measures and features for times series classification

چکیده
Time series classification is a growing problem in different disciplines due to the progressive digitalization of world. The best state-of-the-art algorithms focus on performance, seeking possible results, leaving interpretability at second level, if any. Furthermore, interpretable proposals are far from providing competitive results. In this work, focused time classification, we propose new representation based robust and complete set features. This allows extracting more meaningful information underlying structure develop effective classifiers whose results much easier interpret than current models. proposed feature using traditional vector-based problems, significantly increasing number techniques available for type problem. To evaluate performance our proposal, have used repository UCR, composed 112 datasets. experimental show that through representation, can be obtained which competitive. More specifically, they obtain no statistically significant differences third-best models state-of-the-art. Apart accuracy, proposal able improve model features proposed.

Complexity Measures and Classification Learning
In classification learning experiments, test subjects are presented with objects which they must categorize. The correct categories, which are known to the experimenter, are functions of the characteristics (“dimensions”) of the objects, such as size, color, brightness, and saturation. The experiments measure the relative difficulty of learning different categorizations. One major factor which ...
متن کاملComplexity Measures of Supervised Classification Problems
ÐWe studied a number of measures that characterize the difficulty of a classification problem, focusing on the geometrical complexity of the class boundary. We compared a set of real-world problems to random labelings of points and found that real problems contain structures in this measurement space that are significantly different from the random sets. Distributions of problems in this space ...

congestive heart failure (chf) remains to be one of the major cardiovascular disorders in the world. due to the prevalence of chf related issues, it is prudent to seek out new prognostic predictors that would facilitate the prevention, monitoring, and treatment of the disease on a daily basis. a detection approach using entropy measures extracted from surface electrocardiograms (ecgs) and class...
متن کاملA Comparative Classification of Complexity Measures
A number of different measures of complexity have been described, discussed, and applied to the logistic map. A classification of these measures has been proposed, distinguishing homogeneous and generating partitions in phase space as well as structural and dynamical elements of the considered measure. The specific capabilities of particular measures to detect particular types of behavior of dy...
متن کاملAn Empirical Evaluation of Similarity Measures for Time Series Classification
Time series are ubiquitous, and a measure to assess their similarity is a core part of many computational systems. In particular, the similarity measure is the most essential ingredient of time series clustering and classification systems. Because of this importance, countless approaches to estimate time series similarity have been proposed. However, there is a lack of comparative studies using...
