| Abstract: | The preprocessing of data stream is mainly carried out on the raw data,including interpolating the missing data and excluding the useless data on the monitoring original data set.It is an important and essential part on the data stream preprocessing.Data stream preprocessing can improve the quality of monitoring data stream,and can improve the accuracy and performance of the subsequent processing. |
