Review for NeurIPS paper: Parameterized Explainer for Graph Neural Network

Weaknesses: The work has a certain tendency to misrepresent the literature for the sake of highlighting the originality and impact of this paper. I do not particularly appreciate this type of approach to a scientific paper. More specifically, I strongly invite the Authors to reconsider the following aspects: - Multi-instance Vs Single-Instance: much of the introduction and motivation of the paper is devoted to stating that multi-instance interpretability is the only desired interpretation one would like to have. This is false, if only for a very practical aspect: general data protection regulations require the right of explanation on the "single" prediction. The one that pertains the single individual and the single decision that has been automatically taken by a computational model. Than is single instance explainability and it is very important to develop methodologies and methods for it.
