PELT(Pruned Exact Linear Time)算法是一种基于动态规划的断点检测算法,在实际应用中被广泛使用。 PELT算法的主要思想是将时间序列数据分解成多个子序列,通过计算每个子序列的变化程度,找出突变点。PELT算法的优势在于可以准确地确定突变点的位置,而且计算效率高。在实际应用中,PELT算法可用于信号处理、金融分析、生物学...
The pruned exact linear time change point detection method (PELT) and the disturbance lag model (DLM) were used to understand the detailed ecological coverage status and time lag relationships between the EVI and climatic factors. The results indicate the following. (1) At the whole regional ...
