摘要
Abstract
K-mean clustering algorithm based on fingerprint is divided the reference point into K subclass.The similar objects are clustered together to reduce the search space and im-prove the efficiency.In this paper,we weighted the nearest neighbor of the choose subclass based on the K-means clustering algorithm.Increase the proportion of high correlation refer-ence point while calculating,so as to achieve the purpose of improving the accuracy of loca-tion.The experimental results show that the accuracy of the new algorithm has improved 18.5 percent.关键词
