| 摘 要： | 基于概念格理论,研究了对时间序列的波动情况进行周期关联规则的挖掘.首先对时间序列进行了反季节化预处理,然后提出了生成周期关联规则的新并行算法,在算法内部对生成的概念进行了剪枝处理,有效地提高了挖掘速度.随后用所给出的高精度模型对不满足移动平均法反季节化预处理条件的时间序列进行了反季节化计算.实验证明了该方法的有效性.

| Abstract: | This paper presented a method of cycle association rules mining for time-series fluctuations based on the concept lattice theory.The time-series were first deseasonalized and then a new parallel algorithm of cycle association rules mining was proposed.To increase the mining speed efficiently,some concepts obtained in the algorithm were pruned.Afterward,deseasonalizeation of time-series which do not satisfy the pretreatment conditions of deseasonalizeation in moving average method was computed by a high accu... |
