As such, clustering does not use previously assigned class labels, except perhaps for verification of how well the clustering worked. This kind of algorithmic idea can be also applied to calculating the information entropy of merging result of two clusters. Therefore, since michael porter published his famous book called the competitive advantage of nations in 1990, the analysis and policy initiatives aimed at. Hierarchical clustering dendrograms introduction the agglomerative hierarchical clustering algorithms available in this program module build a cluster hierarchy that is commonly displayed as a tree diagram called a dendrogram. Thus, it is perhaps not surprising that much of the early work in cluster analysis sought to create a. Row i of merge describes the merging of clusters at step i of the clustering.
