In this Supplementary Material we first present details of the Shapley value sampling Appendix A)

In this section, we introduce the details of the Shapley value sampling. We sample the Shapley value for models trained on CIFAR10, CIFAR100 and ImageNet. For CIFAR10 and CIFAR100, we employ ResNet-18 and train them ourselves. For ImageNet, we employ standard ResNet-50 provided in robustbench [11]. We demonstrate more Shapley V alue Quantification Results on ImageNet and TinyImageNet in Figure 1 and Figure 1.
