torchsom: The Reference PyTorch Library for Self-Organizing Maps

This paper introduces torchsom, an open-source Python library that provides a reference implementation of the Self-Organizing Map (SOM) in PyTorch.

This package offers three main features: (i) dimensionality reduction, (ii) clustering, and (iii) friendly data visualization.

It relies on a PyTorch backend, enabling (i) fast and efficient training of SOMs through GPU acceleration, and (ii) easy and scalable integrations with PyTorch ecosystem.

Moreover, torchsom follows the scikit-learn API for ease of use and extensibility.

The library is released under the Apache 2.0 license with 90% test coverage, and its source code and documentation are available at this https URL.
