shap.plots.waterfall(explainer(x)[0],show=False)左边的字体(斜体、下标)怎么设置
import matplotlib.pyplot as plt
import shap
# 创建SHAP解释器
explainer = shap.Explainer(model, X_train)
# 绘制shap.waterfall图
fig = shap.plots.waterfall(explainer(x)[0], show=False)
# 设置左边轴的字体样式
ax_left = fig.axes[0]
ax_left.set_ylabel('字体样式设置', fontsize=12, fontstyle='italic', fontweight='bold')
# 显示图形
plt.show()
这个示例只是演示如何设置字体样式。您需要根据实际需要自定义字体样式
该回答引用ChatGPTpython
import shap
# 生成 shap 值
explainer = shap.Explainer(model)
shap_values = explainer(X)
# 设置自定义特征名称和值
feature_names = ['feature_1', 'feature_2', 'feature_3']
feature_values = [r'$\mathcal{N}(0, 1)$', r'$\hat y \times \mathcal{P}(z)$', r'$\frac{1}{1 + e^{-x}}$']
# 绘制 waterfall 图
shap.plots.waterfall(shap_values[0], max_display=10, feature_names=feature_names, feature_display_values=feature_values)
