WebIn the k-means cluster analysis tutorial I provided a solid introduction to one of the most popular clustering methods. Hierarchical clustering is an alternative approach to k-means clustering for identifying groups in the dataset. It does not require us to pre-specify the number of clusters to be generated as is required by the k-means approach.

WebOn the other hand, if clustering is being used to find meaningful structure in data, then there really is no simple way to know what k ought to be. In fact, there isn’t necessarily a “right” value of k. In the picture below, should k be 2, or 3, or 12? One way to avoid this problem is to do a hierarchical clustering of the data. Webhierarchical clustering was based on providing algo-rithms, rather than optimizing a speci c objective, [19] framed similarity-based hierarchical clustering as a combinatorial …
