Hierarchical clustering is a method of cluster analysis which seeks to build a hierarchy of clusters The quality of a pure hierarchical clustering method suffers from

Many different approaches to hierarchical analysis from divisive The proce- dure ensures that the example is assigned to a wrong cluster with probability 0 1
To illustrate how to perform HCA using R, we simulated a worked example In the example, there are five variables (x1 to x5) represented by columns Each row
This chapter presents the basic concepts and methods of cluster analysis In For example, in text mining, we may want to organize a corpus of documents Hierarchical clustering methods can be distance-based or density- and continuity -

One example is kmeans, a partitioning algorithm, where a required input parameter is the value k for how many clusters are to be found In the density
