Four knowledgeable referees all recommended that the paper be accepted. The reviewers appreciated the many answers provided by the author’s in the rebuttal. After the rebuttal, the reviewers did continue to have concerns about (among other things) the strong assumptions made in the paper. While I agree with the reviewers in these concerns, they and I both concur that the paper makes a publishable contribution in NeurIPS. I recommend that the paper be accepted for poster presentation. I recommend that the authors address the clarifications they promised in their reviews along with the other points made by the reviewers.
