WebbShapley值给了一个理论基础扎实的重要性定义,但是Shapley值的计算一直是一个很大的问题(指数级复杂度),这也带来了很大的限制。我们通过将Shapley值直接作为神经网络 … Webb22 juli 2024 · I believe this paper by Aas et al. (2024) answers your questions, so I will include quotes from it (italicized):. The original Shapley values do not assume independence. However, their computational complexity grows exponentially and becomes intractable for more than, say, ten features.. That's why Lundberg and Lee (2024) …

SHAP(SHapley Additive exPlanation)についての備忘録 - Qiita
Webb30 mars 2024 · SHAP paper² describes two model-agnostic approximation methods, one that is already known (Shapley sampling values) and another that is novel & is based on … Webb25 apr. 2024 · To address this problem, we present a unified framework for interpreting predictions, SHAP (SHapley Additive exPlanations). SHAP assigns each feature an importance value for a particular prediction. Its novel components include: (1) the identification of a new class of additive feature importance measures. … WebbSHAP将Shapley值解释表示为一种 加性特征归因方法 (additive feature attribution method),将模型的预测值解释为二元变量的线性函数: 其中 , 是简化输入的特征数, LIME 就是直接在局部应用上式提供可解释性,把简化的输入 作为可解释的输入,用 把表示可解释输入的二元向量映射到原始输入空间。 在局部上,使 时 DeepLIFT 对神经网络每 … culinary gifts for men
