改进小波聚类算法在QAR数据中的应用
Application of Improved Wavelet Clustering Algorithm in QAR Data
摘要
Abstract
Traditional wavelet clustering algorithm labels the communication unit satisfying density threshold as the same cluster,the mesh which does not meet the density threshold may have the data objects belonging to the cluster,and each dimension attribute of the data sometimes has a big gap,so that subdividing the mesh into uniform grid is not appropriate.Thus,an improved wavelet clustering algorithm is proposed.The method is used to divided the non-uniform grid,and refines further the boundary of the grid which does not satisfy the density threshold,and formats the clusters finally.By applying on the specified Quick Access Recorder (QAR) data sets,experimental results show that the improved wave cluster algorithm can effectiveing distinguish between cluster and boundary of the cluster,according to the characteristics of the data mesh,this method solves the question of the QAR data anomaly detection effectively.关键词
