SuSi: Supervised Self-organizing maps in Python

Python package for unsupervised, supervised and semi-supervised self-organizing maps (SOM)

Description

We present the SuSi package for Python. It includes a fully functional SOM for unsupervised, supervised and semi-supervised tasks:

• SOMClustering: Unsupervised SOM for clustering
• SOMRegressor: (Semi-)Supervised Regression SOM
• SOMClassifier: (Semi-)Supervised Classification SOM

Installation

Pip

pip3 install susi

Conda

conda install -c conda-forge susi

More information can be found in the installation guidelines.

Examples

A collection of code examples can be found in the documentation. Code examples as Jupyter Notebooks can be found here:

• examples/SOMClustering
• examples/SOMRegressor
• examples/SOMRegressor_semisupervised
• examples/SOMRegressor_multioutput
• examples/SOMClassifier
• examples/SOMClassifier_semisupervised

FAQs

• How should I set the initial hyperparameters of a SOM? For more details on the hyperparameters, see in documentation/hyperparameters.
• How can I optimize the hyperparameters? The SuSi hyperparameters can be optimized, for example, with scikit-learn.model_selection.GridSearchCV, since the SuSi package is developed according to several scikit-learn guidelines.
