属性相似度在聚类算法中的有效性研究
ON EFFECTIVENESS OF ATTRIBUTE SIMILARITY IN CLUSTERING ALGORITHM
摘要
Abstract
Euclidean distance identifies the distinctions of different property (i.e. each index or variables) of individuals but neglects the importance of them. To solve this, considering the geometric structure characteristics and the individual property of data and in combination with Mahalanobis distance, we present a new property similarity metric method and the new clustering validity function, and improve the hierarchical clustering algorithm using Euclidean distance. Experiment results show that the improved clustering algorithm can enhance the speed and quality of clustering, and is an effective clustering method.关键词
