WebThe working of the AHC algorithm can be explained using the below steps: Step-1: Create each data point as a single cluster. 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. WebHierarchical Clustering uses the Euclidean distance as the similarity measure for working on raw numeric data. When the data is binary, the remaining two options, Jaccard's coefficients and Matching coefficients, are enabled. Suppose we have binary values for xij. See the table below for individual i and j values. The most useful similarity ...
