Webb22 juli 2024 · 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) proposed using an approximation with the Kernel SHAP method, which is much faster, but assumes independence as shown in … Webb2 juli 2024 · The Shapley value is the average of all the marginal contributions to all possible coalitions. The computation time increases exponentially with the number of features. One solution to keep the computation time manageable is to compute … Webb23 juli 2024 · The Shapley value is one of the most widely used model-agnostic measures of feature importance in explainable AI: it has clear axiomatic foundations, is guaranteed … i\u0027m working from home today
