Webb6 dec. 2024 · SHAP 属于模型事后解释的方法,它的核心思想是计算特征对模型输出的边际贡献,再从全局和局部两个层面对“黑盒模型”进行解释。 SHAP构建一个加性的解释模型,所有的特征都视为“贡献者”。 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。 基本思想:计算一个特征加入到模型时的边际贡献, …

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 Webb14 jan. 2024 · The SHAP Python library has the following explainers available: deep (a fast, but approximate, algorithm to compute SHAP values for deep learning models based on the DeepLIFT algorithm); gradient (combines ideas from Integrated Gradients, SHAP and SmoothGrad into a single expected value equation for deep learning models); kernel (a … hunters bar limerick menu
