corresponding point

According to the numbers of segmentations , dts has multi scale feature and can reflect different trend similarity of time series under various analyzing frequency . 2 ) an enhanced algorithm , based on dual threshold value , and the conception of sub - series linear are proposed . relative point average error is used to measure the linear degree of sub series , which produced by bottom _ up algorithm
对应时间序列线性分段数目的不同，序列趋势距离具有基于时间的多尺度分析特性，可以有效反应不同分析频率下时间序列的相似程度； 2 )采用相对点平均残差衡量bottom _ up算法划分的子序列线性度，提出子序列线性度概念和一种双误差阀值改进算法，大大提高了趋势序列模型的准确性。
