基于网格结构的CLARANS改进算法
Improved CLARANS Algorithm Based on Grid Structure
摘要
Abstract
In order to improve the accuracy and efficiency of Clustering Large Applications based on Randomized Search(CLARANS) algorithm, this paper combines the idea of data space division which comes from grid-based algorithm Statistical Information Grid(STING), improves the CLARANS algorithm by optimizing the selection of initial node and neighbor node, optimizing the calculation of total node replaces cost. Experimental results show that, compared with the CLARANS algorithm, the improved algorithm has better accuracy and stability for the clustering results, and significantly reduce the execution time.关键词
