WebbThe Shapley summary plot colorbar can be extended to categorical features by mapping the categories to integers using the "unique" function, e.g., [~, ~, integerReplacement]=unique(originalCategoricalArray). For classification problems, a Shapley summary plot can be created for each output class. Webb7 nov. 2024 · shap.summary_plot (rf_shap_values, X_test) Feature importance: Variables are ranked in descending order. Impact: The horizontal location shows whether the effect of that value is associated with a higher or lower prediction. Original value: Color shows whether that variable is high (in red) or low (in blue) for that observation.

WebbThe summary plot (a sina plot) uses a long format data of SHAP values. The SHAP values could be obtained from either a XGBoost/LightGBM model or a SHAP value matrix using shap.values. So this summary plot function normally follows the long format dataset obtained using shap.values. If you want to start with a model and data_X, use shap.plot ... Webbshap.bar_plot(shap_values=shap_values[1][3860,:],feature_names=use_cols) 可以看到，未识别样本的各特征贡献上与低风险样本类似，这也是造成模型误判的原因。 再来看概括图，即 summary plot，该图是对全部样本全部特征的shaple值进行求和，可以反映出特征重要性及每个特征对样本正负预测的贡献。 WebbSHAPforxgboost. This package creates SHAP (SHapley Additive exPlanation) visualization plots for ‘XGBoost’ in R. It provides summary plot, dependence plot, interaction plot, and force plot and relies on the SHAP implementation provided by ‘XGBoost’ and ‘LightGBM’. birth matters book
