### Summary

This repository contains 
**py**(**S**tructure-**I**nformed **P**rediction of 
**F**ormation **E**nergy using **N**eural **N**etworks) software 
package allowing efficient predictions of the energetics of 
atomic configurations. The underlying methodology and implementation
is given in

- Adam M. Krajewski, Jonathan W. Siegel, Jinchao Xu, Zi-Kui Liu,
Extensible Structure-Informed Prediction of Formation Energy with improved accuracy and usability employing neural networks,
Computational Materials Science,
Volume 208,
2022,

https://doi.org/10.1016/j.commatsci.2022.111254

While functionalities are similar to the software released along the 
paper, this package contains improved methods for featurizing atomic 
configurations. Notably, all of them are now written completely in 
Python, removing reliance on Java and making extensions of the software
much easier thanks to improved readability. A fuller description of capabilities is 
given in documentation at https://pysipfenn.org and at PSU Phases 
Research Lab webpage under https://phaseslab.com/sipfenn.

### Applications

pySIPFENN in a very flexible tool that can, in principle be used, for prediction of 
any property of interest that depends on an atomic configuration, with very little 
modifications. The models shipped by default are trained to predict formation energy
because that is what our research group is interested in; however, if one wanted to 
predict Poisson's ratio and trained a model based on the same features, adding it
would take minutes. Simply add the model in open ONNX format and link it using 
_models.json_ file, as described in documentation.

### Real-World Examples

In oru line of work, pySIPFENN and formation energies it predicts are usually used 
as a computational engine that generates proto-data for creation of thermodynamic
databases (TDBs) using ESPEI (https://espei.org). The TDBs are then used through
pycalphad (https://pycalphad.org) to predict phase diagrams and other thermodynamic
properties. 

Another of its uses in our research is guiding the Density Functional Theory (DFT)
calculations as a low-cost screening tool. Their efficient conjunction then drives
experiments leading to discovery of new materials as presented in these two papers:

### Install pySIPFENN

Installing pySIPFENN is simple and easy utilizing either **PyPI** package repository or cloning from **GitHub**. 
While not required, it is recommended to first set up a virtual environment using venv or Conda. This ensures that 
one of the required versions of Python (3.9+) is used and there are no dependency conflicts. If you have Conda 
installed on your system (see instructions at https://docs.conda.io/en/latest/miniconda.html), you can create a 
new environment with:

    conda create -n pysipfenn-workshop python=3.9 jupyter
    conda activate pysipfenn-workshop

And then simply install pySIPFENN from PyPI with

    pip install pysipfenn

Alternatively, you can also install pySIPFENN in editable mode if you cloned it from GitHub like

    git clone https://github.com/PhasesResearchLab/pySIPFENN.git

Or by downloading a ZIP file. Please note, this will by default download the latest development version of the 
software, which may not be stable. For a stable version, you can specify a version tag after the URL with
`--branch <tag_name> --single-branch`.

Then, move to the pySIPFENN folder and install in editable (`-e`) mode

    cd pySIPFENN
    pip install -e .
