Explanations of model predictions with live and breakDown packages
This work addresses the need for interpretability in predictive modeling for users of complex models, though it is incremental as it builds on existing state-of-the-art solutions.
The authors tackled the problem of explaining predictions from complex black-box models by introducing two new R packages, live and breakDown, for attributing predictions to input features, and compared them with existing methods like lime and ShapleyR, showing competitive results.
Complex models are commonly used in predictive modeling. In this paper we present R packages that can be used to explain predictions from complex black box models and attribute parts of these predictions to input features. We introduce two new approaches and corresponding packages for such attribution, namely live and breakDown. We also compare their results with existing implementations of state of the art solutions, namely lime that implements Locally Interpretable Model-agnostic Explanations and ShapleyR that implements Shapley values.
