As the name itself suggests, Clustering algorithms group a set of data points into subsets or clusters. The algorithms' goal is to create clusters that are coherent internally, but clearly different from each other externally. In other words, entities within a cluster should be as similar as po...
In this post, I will show you how to do hierarchical clustering in R. We will use the iris dataset again, like we did for K means clustering. What is hierarchical clustering? If you recall from the post about k means clustering, it requires us to specify the number of clusters, and ...

In the complete linkage, also called farthest neighbor, the clustering method is the opposite of single linkage. Distance between groups is now defined as the distance between the most distant pair of objects, one from each group. In the complete linkage method, D(r,s) is computed as D(...
Alternative Methods to Hierarchical Clustering In Displayr, hierarchical cluster analysis treats the variables as the cases, meaning it is used to create segments of products, brands, etc. If your aim is to group similarrespondentstogether, you should consider the following alternatives: ...

Hierarchical clustering is a common algorithm in data analysis. It is unique among several clustering algorithms as it draws dendrograms through a specific metric and extracts groups of features. It is widely used in all areas of astronomical research, covering systems at various scales, from astero...
