Overview

The ingredients package is a collection of tools for assessment of feature importance and feature effects. It is imported and used to compute model explanations in multiple packages e.g. DALEX, modelStudio, arenar.

The philosophy behind ingredients explanations is described in the Explanatory Model Analysis: Explore, Explain, and Examine Predictive Models e-book. The ingredients package is a part of DrWhy.AI universe.
