Title: Effective time series outlier detection algorithm based on segmentation
Abstract: A new time series outlier detection algorithm of high-efficiency is proposed for the foundation of k-nearest local outlier detection algorithm based on segmentation.Firstly,series important point as segmentation point can compress highproportionally time series data in this algorithm;Secondly,the outlier pattern of time series can be detected by local outlier detection technique.Experimental results on electrocardiogram(ECG) data show that the algorithm is effective and reasonable.
