Periodicity mining is the mining of periodic patterns, that is, the search for recurring patterns in time-series database.
周期模式主要是研究时序数据库中的循环特性，是时态数据挖掘的一个重要的研究方向。
They are the foundation of research on Algorithm of Mining Partial Periodic Patterns and they can be used in the whole paper.
这作为全文研究的基础，贯穿于时间序列部分周期模式挖掘和增量挖掘分析的全过程。
Setting this value closer to 1 favors the discovery of many near-periodic patterns and the automatic generation of periodicity hints.
如果将此值设置为更接近于1的数，则允许查找许多接近周期的模式并允许自动生成周期提示。
