Multiple time granularity partial periodicity model
Yu Cheng · Jisuanji gongcheng yu sheji · 2007
The description and division of time is a very important aspect;For resolving the problem of lacking research of multiple time granularity at present,a mathematical concepts of multiple time granularity,granularity transform and temporal series is presented.The relationships and properties of model is proved.A multiple time granularity partial periodicity model is introduced based on those.At the same time,the support and confidence properties of model is discussed and is applied to the stock data experiment,which is significant in study of the temporal data mining.
