Anomaly subsequence detection is to detect inconsistent data, which always contains important information, among time series. Due to the high dimensionality of the time series, traditional anomaly detection often requires a large time overhead; furthermore, even if the dimensionality reduction techniques can improve the efficiency, they will lose some information and suffer from time drift and parameter tuning. In this paper, we propose a new anomaly subsequence detection with Dynamic Local…

Anomaly detection in time series based on interval sets

The experimental results indicate that the proposed anomaly detection algorithm, called probability interval, has better discriminative performance than the piecewise aggregate approximation method and greatly reduces the false alarm rate.
