Webbdifferent impurity profiles in a grown crystal, generating a core rich in impurities and an increasing purity as we approach the crystal surface.52 These mechanisms will lead to a heterogeneous distribution of impurities within the crystal lattice (Fig. 2), with some areas of the crystal presenting impurity concentrations orders of magnitude WebbMoreover, impurity-based feature importance for trees are strongly biased in favor of high cardinality features (see Scikit-learn documentation). Since fit-time importance is model-dependent, we will see just examples of methods that are valid for tree-based models, such as random forest or gradient boosting, which are the most popular ones.
