Incorporating notions of "vacuity" and "dissonance" in active learning is novel, and reviewers are convinced of its improvements. The empirical evaluation regarding certain baselines and scale are a bit lacking, and while the work may be sufficient for acceptance, the reviews all believe the work would at least benefit from further discussion to related work in the paper revision: Prior Networks and Noise Contrastive Priors. In addition, promoting more discussion on the need for Dempster-Schafer as R1 asks, is very welcome. I congratulate the authors!
