Study of distance-measuring method and application for time series similarity search based on slope departure
基于斜率偏离的时间序列相似性搜索方法研究*

Aiming at the measuring method of similarity search in time series, this paper proposed a similarity measuring method based on slope departure. To dispose the time series data with high dimension, used a similarity measuring method to caculate the slope departure based on curve-in bin solving the localization of slope distance measurement in SFFS. In fact, the physical concept of this method proved more clearly and nicely with real fight data. The maturity, validity and the continuity of slope departure was proved.
