Abstract
This paper presents a multi-density incremental clustering algorithm based on grid ( MICG) , the discriminant function taking into account relative density and gravity distance between grid cells is introduced. When a portion of the data sets changed, without re-clustering all the data, this algorithm could formulate a new cluster according to original clustering result merely based on the relationship between the unit with changed data set and neighbored unit. This approach effectively improved efficiency of cluster analysis. The time complexity and space complexity are linear with the size of dataset and the number of attributes. The experimental results show that MICG algorithm can process cluster with any shape or different densities, and can solve the incre-ment clustering problem effectively when the data is updated.关键词
