提出了一种基于空间单元单维运算的快速聚类算法SUSDC。该算法首先将被聚类的数据逐维划分成若干个不相交的空间单元;然后基于空间距离阂值判定相邻的空间单元是否合并,直到全部维处理完毕。实验结果验证了SUSDC算法运算速度快,能够处理不规则形状数据和高维数据,且具有对噪声数据不敏感的特点。
This paper proposed a rapid clustering algorithm based on spatial unit single dimensional calculation (SUSDC). The algorithm firstly divided data to orthogonal spatial units, and then clustered spatial units by spatial distance threshold. Experimental results show that SUSDC algorithm can deal with clusters of complicated shaped and high-dimensional data, and it has high-efficient features and is not sensitive to noise data.
