This paper was reviewed by three experts in the field and received 677 recommendations. Based on the reviewers' feedback, the decision is to recommend the paper for acceptance to NeurIPS 2019. The reviewers did raise some valuable concerns especially on the citing related works for the transductive part and the additional experiments and analyses suggested (and provided in the rebuttal). These questions should be addressed in the final camera-ready version of the paper. The authors are encouraged to make the necessary changes to the best of their ability. We congratulate the authors on the acceptance of their paper!
