%description
Complex machine learning models are often hard to interpret. However, in
many situations it is crucial to understand and explain why a model made a
specific prediction. Shapley values is the only method for such prediction
explanation framework with a solid theoretical foundation. Previously
known methods for estimating the Shapley values do, however, assume
feature independence. This package implements methods which accounts for
any feature dependence, and thereby produces more accurate estimates of
the true Shapley values. An accompanying 'Python' wrapper ('shaprpy') is
available through the GitHub repository.
