Shapley feature importance code
Webb18 mars 2024 · Shapley values calculate the importance of a feature by comparing what a model predicts with and without the feature. However, since the order in which a model sees features can affect its predictions, this is done in every possible order, so that the features are fairly compared. Source SHAP values in data
