HiPart: Hierarchical divisive clustering toolbox

This repository presents the HiPart package, an open-source native python library that provides efficient and interpretable implementations of divisive hierarchical clustering algorithms. HiPart supports interactive visualizations for the manipulation of the execution steps allowing the direct intervention of the clustering outcome. This package is highly suited for Big Data applications as the focus has been given to the computational efficiency of the implemented clustering methodologies. The dependencies used are either Python build-in packages or highly maintained stable external packages. The software is provided under the MIT license.

Installation

For the installation of the package, the only necessary actions and requirements are a version of Python higher or equal to 3.8 and the execution of the following command.

pip install HiPart

Simple Example Execution

The example bellow is the simplest form of the package's execution. Shortly, it shows the creation of synthetic clustering dataset containing 6 clusters. Afterwards it is clustered with the DePDDP algorithm and only the cluster labels are returned.

from HiPart.clustering import DePDDP
from sklearn.datasets import make_blobs

X, y = make_blobs(n_samples=1500, centers=6, random_state=0)

clustered_class = DePDDP(max_clusters_number=6).fit_predict(X)

Users can find complete execution examples for all the algorithms of the HiPart package in the clustering_example file of the repository. Also, the users can find a KernelPCA method usage example in the clustering_with_kpca_example file of the repository. Finally, the file interactive_visualization_example contains an example execution of the interactive visualization. The instructions for the interactive visualization GUI can be found with the execution of this visualization.
