Shap kernel explainer
Webb这是一个相对较旧的帖子,带有相对较旧的答案,因此我想提供另一个建议,以使用 SHAP 确定特征对Keras模型的重要性. SHAP与当前仅支持2D数组的eli5相比,2D和3D阵列提供支持(因此,如果您的模型使用需要3D输入的层,例如LSTM或GRU,eli5将不起作用). 这是 WebbHere we repeat the above explanation process for 50 individuals. Since we are using a sampling based approximation each explanation can take a couple seconds depending on your machine setup.

The computed importance values are Shapley values from game theory and also coefficents from a local linear regression. Parameters ---------- model : function or iml.Model
