Before revision:  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  .
After revision:  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 . Complex classifiers are frequently found to be responsible for both correct and incorrect classification decisions .
