WitrynaThe steps to perform the same is as follows −. Step 1 − Treat each data point as single cluster. Hence, we will be having, say K clusters at start. The number of data points will also be K at start. Step 2 − Now, in this step we need to form a big cluster by joining two closet datapoints. This will result in total of K-1 clusters. http://sigmaquality.pl/data-plots/dendrogram-and-clustering-3d/
