Finding the potential spatiotemporal co-occurrence behavior patterns of large groups of ships while sailing is a challenging problem Collections of great importance in many real-world applications.Through spatiotemporal data mining of ship trajectory data, route rules, navigation behavior, and potential anomalies can be mined, providing important s
Time-series #3.44 DARK COPPER BROWN data often have an abrupt structure change at an unknown location.This paper proposes a new statistic to test the existence of a change-point in a multinomial sequence, where the number of categories is comparable with the sample size as it tends to infinity.To construct this statistic, the pre-classification is
As the next-generation grid, the 2 Layers Wood Sign smart grid (SG) can significantly enhance the reliability, flexibility as well as efficiency of electricity services.To address latency and bandwidth issues during data analysis, there have been attempts to introduce fog computing (FC) in SG.However, fog computing-based smart grid (FCSG) face seri
