示例1: dimensionsUpdateFrequencyEstimation

# 需要导入模块: from library.classes import GeneralMethods [as 别名]
# 或者: from library.classes.GeneralMethods import approximateToNearest5Minutes [as 别名]

     '''
     Observe the new dimensions that get added to current dimension if the dimensions 
     are being updated at regular intervals.
     For example, number of dimensions being added after 10m, 20m,... 5 horus. 
     As time increases the number of 'decayed' dimensions increase. The current dimensions
     has a lot of unwanted decayed dimensions. Using this information identify the time 
     interval that is best suited to refresh dimensions. 
     Tentative: We decide to pick the time interval at which the rate of decay is maximum.
