| Abstract: | RFID raw data have the characters of mass and uncertainty.Through the analysis of the uncertain data timing relationship,the data cleaning algorithms aimed at different cleaning nodes are proposed.The RFID data are seen as the time series data according to time characteristics and the kind of algorithms also break the traditional cleaning method based on the response count of tags.The experimental results show that the proposed algorithms can be extended easily and improve the accuracy of data cleaning effectively. |
