总体解释 在Python的大多数模型中,总体解释已经开箱即用,具有“feature_importances_”属性。示例如下: from sklearn.ensemble import RandomForestClassifier # from xgboost import XGBClassifier model = RandomForestClassifier() # XGBClassifier() model.fit(X, y) pd.DataFrame({'Variable':X.columns, 'Importanc...
XGBoost的特征选择属于特征选择中的嵌入式方法,在XGboost中可以用属性feature_importances_去查看特征的重要度。 ? sns.barplot Signature: , sns.barplot( , x=None, , y=None, , hue=None, , data=None, , order=None, , hue_order=None, , estimator=<function mean at 0x7f5030185950>, , ci=95, ...

If we look at the feature importances returned by XGBoost we see that age dominates the other features, clearly standing out as the most important predictor of income. We could stop here and report to our manager the intuitively satisfying answer that age is the most important feature, followed...
(PI) and SHAP. Figure5compares the results of these ML interpretation methods. In this case, PI provides a global overview of the feature importance in the XGBoost regression model. Comparatively, SHAP allows for a more granular understanding of feature effects at the level of individual ...

Research limitations/implications: XGBoost, A ceteris paribus plot, SHAP, and feature importance methods can be used to develop a credit risk assessment model including machine learning interpretability. The main limitation of research is to compare the results of XGBoost only to the logistic ...
In addition, the BO-XGBoost model enhanced interpretability through an accessible analysis of feature importance, identifying volume loss as the most critical factor affecting settlement predictions. Using the prediction model and a particle ... L Peng - 《Sustainability》 被引量: 0发表: 2024年 Inte...
