基于动态滑动窗口的改进数据流聚类算法
Improved data stream clustering algorithm over sliding window
摘要
Abstract
An optimization algorithm DCluStream was proposed which processed data over sliding window. The method adopted online-offline clustering framework of CluStream.The real time of the data object coming and out of sliding window was introduced into the characteristics of the cluster,adjusting the win-dow size reasonably in the limited memory resources environment.Using the time decay mechanism on his-torical data could reduce the impact of new data object,which could get better clustering results.The exper-imental results showed that compared with the algorthm CluStream,data processing efficiency of the algo-rithm was relatively higher with saving memory.关键词
