This repository contains PyTorch extensions to compute persistent homology and to differentiate through the persistent homology computation. The packaging structure is similar to PyTorch's structure to facilitate usage for people familiar with PyTorch.

Documentation

Read the docs!

The folder tutorials (within docs) contains some (more or less) minimalistic examples in form of Jupyter notebooks to demonstrate how to use the PyTorch extensions.

If you use any of these extensions, please cite the following works (depending on which functionality you use, obviously :)
