YU Ting-ting · Zhejiang Hydrotechnics · 2004
This paper adopts differential information theory to identify change points in time series. Key step of variation identification is to build up comparing sequence and two methods are introduced. One is comparing series formed of moving partition step by step; another is comparing series formed of order clustering optimum bi-partition. The two means are applied in analysis change point of annual maximum tidal level series at Ganpu station and get the unanimous result.
