Anomaly Subsequence Detection with Dynamic Local Density for Time Series
Chunkai Zhang, Yingyang Chen, Ao Yin
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, tra…

An Improvement of PAA on Trend-Based Approximation for Time Series
Chunkai Zhang, Yingyang Chen, Ao Yin +4
Piecewise Aggregate Approximation (PAA) is a competitive basic dimension reduction method for high-dimensional time series mining. When deployed, however, the limitations are obvio…
