Given that most of those methods strongly depend on the initialization of the clusters, we expect this to be a rather unstable approach. Therefore, we use hierarchical clustering methods, which are not dependent on the initialization of the ...

WebHierarchical clustering is an unsupervised learning method for clustering data points. The algorithm builds clusters by measuring the dissimilarities between data. Unsupervised learning means that a model does not have to be trained, and we do not need a "target" variable. This method can be used on any data to visualize and interpret the ... Web1.

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. entry preparation
