## Definition
|
||
SHAP(SHapley Additive exPlanations)是一种基于博弈论的模型可解释性方法,用于分解单个预测中每个特征的贡献。
|
||
|
||
## Outputs
|
||
- 全局解释:summary / beeswarm / bar plot
|
||
- 局部解释:waterfall / force plot
|
||
- 交互分析:SHAP interaction values
|
||
|
||
## Use in Model QA
|
||
- 解释预测驱动因素
|
||
- 检查特征贡献是否稳定
|
||
- 识别异常依赖或潜在偏差
