Reviews: XNAS: Neural Architecture Search with Expert Advice

The reviewers appreciated the good empirical results and theoretical analysis. This paper proposes to treat NAS problems as a selection problem among experts. Over time, it eliminates underperforming experts with a wipe-out step. As two of the reviewers pointed out, the theoretical analysis is interesting (and rare, in this type of paper), but it would be good to more explicitly spell out when and why the assumptions hold. Empirical performance seems good, but the authors should include error bars for at least the CIFAR-10 experiments and ideally the ImageNet ones as well.
