Welcome to GemClus documentation!

Welcome and thank you for checking GEMINI out, this really pleasures us.

GEMINI is a clustering-dedicated function derived from information theory that allows to do clustering without hypotheses on the data distributions. We try to provide overall some implementations of small-scale discriminative clustering methods in this package. These methods include small neural networks, logistic regression, decision trees and work from other paper that we will relevant to the discriminative clustering field in the GEMINI spirit.

GEMCLUS - A package for discriminative clustering using GEMINI

The gemclus package provides simple tools to perform discriminative clustering using the generalised mutual information (GEMINI). The package was written to be a scikit-learn compatible extension.

You can find the complete documentation of the package here: https://gemini-clustering.github.io/

The documentation for the latest updates is at: https://gemini-clustering.github.io/main

The official source code can be found here: https://github.com/gemini-clustering/GemClus


Official package

Use the following instruction for installing the package:

pip install gemclus

The library requires a couple scientific package to run:

  • NumPy

  • Scipy

  • POT

  • Scikit-learn

Latest version

You may download the latest version of the package by installing the content of the repo.

git clone https://github.com/gemini-clustering/GemClus
cd GemClus
pip install .
