brainets/hoi: Higher-Order Interactions · GitHub

HOI (Higher Order Interactions) is a Python package to go beyond pairwise interactions by quantifying the statistical dependencies between 2 or more units using information-theoretical metrics. The package is built on top of Jax allowing computations on CPU or GPU.

HOI requires :

• Python (>= 3.8)
• numpy(>=1.22)
• scipy (>=1.9)
• jax
• pandas
• scikit-learn
• jax-tqdm
• tqdm

To install Jax on GPU or CPU-only, please refer to Jax's documentation : https://jax.readthedocs.io/en/latest/installation.html

If you already have a working installation of NumPy, SciPy and Jax, the easiest way to install hoi is using pip:

pip install -U hoi

You can also install the latest version of the software directly from Github :

pip install git+https://github.com/brainets/hoi.git

For developers, you can install it in develop mode with the following commands :

git clone https://github.com/brainets/hoi.git
cd hoi
pip install -e .['full']

The full installation of HOI includes additional packages to test the software and build the documentation :

• pytest
• pytest-cov
• codecov
• xarray
• sphinx!=4.1.0
• sphinx-gallery
• pydata-sphinx-theme
• sphinxcontrib-bibtex
• numpydoc
• matplotlib
• flake8
• pep8-naming
• black
