Seismic precursory data are generally very complicated.Thus identification of geophysical field changes and elimination of ambient noise is crucial to analysis of the phenomenon associated with earthquakes.Traditional methods,including regression analysis,empirical mode decomposition and signal frequency domain analysis,are not feasible to recognize the changes of high amplitude(peaks and steps)and frequency simultaneously.In this study,the entropy of time series was used to automatically segment deformation time-series data into subsequences,partly avoiding the dissection of waveforms with high amplitude and frequency.Then the subsequences were featured by statistics,and outliers log function through Angle-Based OutlierFactor and Local Density Outlier Factor were defined to solve the problem of recognition of those waveforms.Experimental results show that there is a linear relationship between the efficiency of the algorithm and the changes of feature dimensions.When the dimension of feature changes,the LOF-ABOF algorithm takes effect on the recognition of high amplitude and high frequency.Our method can be used to detect the types of anomalies,which provide the guideline for precursor recognition and lay a foundation for further understanding seismic phenomena and their mechanism.
