We would like to thank reviewers for the constructive feedback and the positive recommendation. While zeroing-out features leads to abrupt change in the model's output, randomizing features6 requires alargenumber ofsamples forstable explanations. The 4 nodes highlighted in Figure 1 of PGM-Explainer is not a mistake. We demonstrate this in the same GNN considered in Fig.1 of the31 manuscript. The models are directly taken from previous work [23] and [32]38 (stated at line 250 and 267).
