基于域变换函数和距离函数时间序列相似性概念体系

Study on time series similarity concept system based on domain, transform-function and distance-function

分析了域、变换函数和距离函数对相似性研究的影响,给出了具体的基于域、变换函数和距离函数的时间序列相似性概念体系,很好的解决了相似性概念的问题。同时,在相似性问题的研究策略上结合给出的相似性概念确定了"自底向上"的研究方式,为时间序列相似性研究工作的系统开展指明了方向。

The paper analyzes the influence of domain,transition function and distance function on similarity research..Gives concrete time series similar concept system based on the domain,the transition function and the distance function,which is a good solution to the similar concept problem.At the same time,the given similar concept is combined in the similar problem research strategy,determining the ‘bottom-up’research way,which indicating the direction for the time series similarity research work.
