It connects optimal credit allocation with local explanations using the classic Shapley values from game theory and their related extensions (see papers for details and citations). Install
WebbSHAP是由Shapley value启发的可加性解释模型。 对于每个预测样本,模型都产生一个预测值,SHAP value就是该样本中每个特征所分配到的数值。 假设第ii个样本为xixi,第ii个样本的第jj个特征为xi,jxi,j,模型对第ii个样本的预测值为yiyi,整个模型的基线(通常是所有样本的目标变量的均值)为ybaseybase,那么SHAP value服从以下等式。 yi=ybase+f … Webb25 dec. 2024 · SHAP or SHAPley Additive exPlanations is a visualization tool that can be used for making a machine learning model more explainable by visualizing its output. It can be used for explaining the prediction of any model by computing the contribution of each feature to the prediction. It is a combination of various tools like lime, SHAPely sampling ...
