hierarchical clustering python

Scikit

Hierarchical clustering is a kind of clustering that uses either top-down or bottom-up approach in creating clusters from data. It either starts with all samples in the dataset as one cluster and goes on dividing that cluster into more clusters or it starts with single samples in the dataset as clusters and then merges samples based on criteria to create clusters with more samples.

Hierarchical clustering algorithm in Python

The steps in hierarchical clustering are: Calculate the NxN distance (similarity) matrix, which calculates the distance of each data point from the other. Each item is first assigned to its own cluster, i.e. N clusters are formed. The clusters which are closest to each other are merged to form a single cluster.

Hierarchical Clustering Algorithm Example in Python

 · Hierarchical Clustering Algorithm Example in Python. Hierarchical Clustering uses the approach of finding groups in the data such that the instances are more similar to each other than to cases in different groups. This similarity measure is generally a Euclidean distance between the data points, but Citi-block and Geodesic distances can also.
