shap.force_plot(explainer.expected_value[1], shap_values[1][0,:], X_display.iloc[0,:])解读
def force(base_value, shap_values=None, features=None, feature_names=None, out_names=None, link="identity", plot_cmap="RdBu", matplotlib=False, show=True, figsize=(20,3), ordering_keys=None, ordering_keys_time_format=None, text_rotation=0, contribution_threshold=0.05):
功能 | Visualize the given SHAP values with an additive force layout. 使用附加力图布局可视化给定的 SHAP 值。 |
参数 | Parameters ---------- base_value : float,This is the reference value that the feature contributions start from. For SHAP values it should be the value of explainer.expected_value. 这是特征贡献开始时的参考值。 对于SHAP值,它应该是 explainer.expected_value 的值。 shap_values : numpy.array,Matrix of SHAP values (# features) or (# samples x # features). If this is a 1D array then a single force plot will be drawn, if it is a 2D array then a stacked force plot will be drawn. SHAP 值矩阵(# features)或(# samples x # features)。 如果这是一维数组,则将绘制单个力图,如果是二维数组,则将绘制堆叠力图。 features : numpy.array,Matrix of feature values (# features) or (# samples x # features). This provides the values of all the features, and should be the same shape as the shap_values argument. 特征值矩阵(# features)或(# samples x # features)。 这提供了所有特征的值,并且应该与shap_values参数的形状相同。 |
