Shapley network
WebbKernel SHAP比Shapley sampling的sampling efficiency高：每一个Shapley sampling的sample按照定义式仅计算一个feature的对应Shapley值，而Kernel SHAP中一个sample计算的是所有feature的Shapley值。 当然还有对应DNN的： Deep SHAP [10] ： 在每一层计算层内的Shapley值，线性层的Shapley值就是输入乘上对应权重。 WebbThe Shapley value of a feature for a query point explains the deviation of the prediction for the query point from the average prediction, due to the feature. For each query point, the …
