WebbUses Shapley values to explain any machine learning model or python function. This is the primary explainer interface for the SHAP library. It takes any combination of a model and masker and returns a callable subclass object that implements the particular estimation algorithm that was chosen. Parameters modelobject or function
Webb17 maj 2024 · explainer = shap.KernelExplainer (model.predict,X_train) Now we can calculate the shap values. Remember that they are calculated resampling the training dataset and calculating the impact over these perturbations, so ve have to define a proper number of samples.
