WebTitle Hierarchical Clustering of Univariate (1d) Data Version 0.0.1 Description A suit of algorithms for univariate agglomerative hierarchical clustering (with a few pos-sible choices of a linkage function) in O(n*log n) time. The better algorithmic time complex-ity is paired with an efficient 'C++' implementation. License GPL (>= 3) Encoding ... WebAvailable online 3 February 2007 Abstract Techniques based on agglomerative hierarchical clustering constitute one of the most frequent approaches in unsupervised clustering. Some are based on the single linkage methodology, which has been shown to produce good results with sets of clusters of various sizes and shapes.

Let's say there are N data points, so the number of clusters will also be N. Step-2: Take two closest data points or clusters and merge them to form one cluster. So, there will now be N-1 clusters.
