Webb14 apr. 2024 · In the linear model SHAP does indeed give high importance to outlier feature values. For a linear (or additive) model SHAP values trace out the partial dependence plot for each feature. So a positive SHAP value tells you that your value for that feature increases the model's output relative to typical values for that feature. Webb14 dec. 2024 · SHAP有两个核心，分别是shap values和shap interaction values，在官方的应用中，主要有三种，分别是force plot、summary plot和dependence plot，这三种应用都是对shap values和shap interaction values进行处理后得到的。. 下面会介绍SHAP的官方示例，以及我个人对SHAP的理解和应用。. 1 ...

WebbThough the dependence plot is helpful, it is difficult to discern the practical effects of the SHAP values in context. For that purpose, we can plot the synthetic data set with a decision plot on the probability scale. First, we plot the reference observation to establish context. The prediction is probability 0.76. 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。
