This repository contains the Python (3.8+) package implementing the Material Optimal Descriptor Network (MODNet). It is a supervised machine learning framework for learning material properties from either the composition or crystal structure. The framework is well suited for limited datasets and can be used for learning multiple properties together by using joint learning.
MODNet appears on the MatBench leaderboard. As of 11/11/2021, MODNet provides the best performance of all submitted models on 7 out of 13 tasks.
This repository also contains two pretrained models that can be used for predicting the refractive index and vibrational thermodynamics from any crystal structure.

First, create a virtual environment (e.g., named modnet) with Python (3.8+) using your favourite environment manager (the following instructions use conda):
conda create -n modnet python=3.9Activate the environment:
conda activate modnetFinally, install MODNet from PyPI with pip:
pip install modnetWarning We strongly recommend pinning your Python environment when using MODNet across multiple machines, or multiple MODNet versions, as changes to the dependencies and sub-dependencies can lead to different values for particular features.
This can be achieved with
conda exportorpip freeze.
For development (or if you wish to use pinned versions of direct dependencies that
MODNet has been tested with), you can clone this git repository and make an
editable install inside your chosen environment with pip:
git clone [email protected]:ppdebreuck/modnet
cd modnet
conda create -n modnet python=3.9
conda activate modnet
pip install -r requirements.txt # optionally use pinned requirements
pip install -e .The documentation is available at ReadTheDocs.
A brief changelog can be found in the release summaries on GitHub.
