Before revision:  Experimental results on graph classification tasks establish that Troupe gives precise estimates of the Shapley value in ensemble games. We demonstrate that the Shapley value can be used for pruning large ensembles, show that complex classifiers have a prime role in correct and incorrect classification decisions, and provide evidence that adversarial models receive a low valuation  .
