Multidimensional cluster analysis

摘要

Disclosed is a method of cluster analysis of a data set of multidimensional observations. The method comprises: determining a set of quasi-optimal binwidths for the data set; partitioning, for a current binwidth in the set of quasi-optimal binwidths, the data set into a plurality of bins of width equal to the current binwidth; determining the number of modes of the partitioned data set for the current binwidth; and repeating the partitioning and determining the number of modes for each binwidth in the set of quasi-optimal binwidths. The number of clusters in the data set is the largest determined number of modes over the set of quasi-optimal binwidths.
