WebbWe propose a novel definition of Shapley values with uncertain value functions based on first principles using probability theory. Such uncertain value functions can arise in the context of explainable machine learning as a result of non-deterministic algorithms.

WebbBased on the decomposition (9), the Shapley values and in-teraction indices are computed as follows. By linearity, the Shapley values can be computed summandwise, i.e. ϕ U(v) = X [A,B] ϕ U(v [A,B]·1 ). (11) So the complexity of computing the Shapley value is the complexity of computing ϕ U(v [A,B]·1 ) times the num-ber of intervals.
