The Shapley value, originally introduced in coalition game theory, has found applications in data management and machine learning, as an explanation score. With it one can assign numerical values to database tuples of feature values, depending on whether we observe a result of a query or a classification, to quantify the relevance of the tuple or the feature value in relation to this result.
