Note that this repository contains the package with the algorithms for the generation of the explanations proposed in the paper and their evaluations but not the expriments themselves. If you are interested in reproducing the results of the paper, please refer to the cf-shap-facct22 repository (that uses the algorithms implemented in this repository).
To install the package manually, simply use the following commands. Note that this package depends on shap>=0.39.0 package: you may want to install this package or the other dependencies manually (using conda or pip).
# Clone the repo into the `cf-shap` directory
git clone https://github.com/jpmorganchase/cf-shap.git
# Install the package in editable mode
pip install -e cf-shapThe package has been tested with Python 3.6 and 3.8, but it is agnostic to the Python version being used.
See setup.py and requirements.txt for more details on the dependencies of the package.
Check out Example.ipynb or Example.html for a basic usage example of the package.
