Segment and Combine Approach for Non-parametric Time-Series Classification

Abstract: Abstract. This paper presents a novel, generic, scalable, autonomous, and flexible supervised learning algorithm for the classification of multivariate and variable length time series. The essential ingredients of the algorithm are randomization, segmentation of time-series, decision tree ensemble based learning of subseries classifiers, combination of subseries classification by voting, and cross-validation based temporal resolution adaptation. Experiments are carried out with this method on 10 synthetic and … Show more

“…Both methods have already proven useful in a number of applications. In particular, problems of very high dimensionality, like image classification problems (Marée et al, 2004), mass-spectrometry datasets (Geurts et al, 2005b), or time-series classification problems (Geurts and Wehenkel, 2005), make the Extra-Trees a first choice method due to its attractive computational performances. Also, the fact that totally randomized trees have a tree structure independent of the output variable has been exploited in the context of reinforcement learning where it ensures the convergence of the reinforcement learning algorithm and leads to a very efficient implementation (Ernst et al, 2005).…”

“…The Extra‐Trees algorithm, a nonparametric tree‐based regression method based on an ensemble of decision trees, has already been applied in many fields such as environmental modeling [ Jung et al ., ] and water reservoir operation [ Castelletti et al ., ]. Because of its efficient computational performance in problems with very high dimensionality [ Geurts et al ., ; Geurts and Wehenkel , ], we selected the Extra‐Trees algorithm to determine the relationships between variables in cascade reservoir operation.…”

“…The methods are effective to analyse time series segments with limited size. Additionally, segment time series can be seen as series representation to summary time series features in [19][20][21]. However, they just can be used to analyse single time series.…”
