摘要: 提出一种双层体系结构用于流数据上的聚类分析. 快速计算层采用快速但粗糙的方法得到中间结果; 精确分析层采用更加复杂的方法对中间结果进行深入分析, 用于发现复杂的聚类. 实验结果显示, 这种结构在满足流数据快速分析要求的基础上能够得到更好的聚类结果.

Abstract: The framework of 2-level structure is proposed to cluster the data streams. The first is quickly computing level by which the intermediate results are gained with the rough but fast algorithm; the second is complex analysis level by which the intermediate results are deeply analyzed with more complicated method to find complex clusters. The empirical evidence shows that with the framework effectively clustering the data streams is performed on the basis of atisfying the demand of rapid analysis of the data streams.

Key words: data streams, cluster, two-tier structure
