Webb4 aug. 2024 · Kernel SHAP is the most versatile and commonly used black box explainer of SHAP. It uses weighted linear regression to estimate the SHAP values, making it a computationally efficient method to approximate the values. The cuML implementation of Kernel SHAP provides acceleration to fast GPU models, like those in cuML. Webb12 aug. 2024 · because: first uses trained trees to predict; whereas second uses supplied X_test dataset to calculate SHAP values. Moreover, when you say. shap.Explainer (clf.best_estimator_.predict, X_test) I'm pretty sure it's not the whole dataset X_test used for training your explainer, but rather a 100 datapoints subset of it.
