Review for NeurIPS paper: Uncertainty Aware Semi-Supervised Learning on Graph Data

R#2 and R#3 generally liked the paper. R#1 has a brief review that raised concern on novelty of the method. The rebuttal well addressed the concerns and made all reviewers increase their score. We have collected comments from an additional reviewer, who pointed out more issues on writing and the theoretical results (see blew). We advise the authors to take efforts to address these issues in the revision.
