| 摘 要： | M-BIRCH算法通过设置多个阈值来弥补BIRCH算法在聚类效率和精度方面存在的不足。针对M-BIRCH算法在阈值设置方面存在的不足,提出将启发式阈值估计方法应用于M-BIRCH,并对算法在树的重建次数的减少和处理时间的缩短方面进行了验证。

| Abstract: | Considering the imperfections of clustering precision and clustering efficiency which exist in the BIRCH algorithm,multi-threshold has been presented in M-BIRCH algorithm.The efficiency of thresholds setting is not exact enough.This paper presents an heuristic algorithm based on multi-threshold BIRCH algorithm,and validates the effect on rebuilding tree times and processing time of the algorithm. |
