This method … WebbTo calculate the Shapley value method we use the predict_parts() function with type = ‘shap’. We need the explainer object and the observation for which we want to calculate the explanation. Webb2 feb. 2024 · SHAP values are average marginal contributions over all possible feature coalitions. They just explain the model, whatever the form it has: functional (exact), or tree, or deep NN (approximate). They are as good as the underlying model. – Sergey Bushmanov Feb 4, 2024 at 14:26 import necessary libraries
