Reviews: Tagger: Deep Unsupervised Perceptual Grouping

UPDATE: I thank the authors for their convincing rebuttal, and in view of the promised updates on the technical specifications and description of the method, I increased the scores for "Technical quality" and "Clarity and presentation". My only major concern I still have is the lack of a suitable baseline to compare with. In particular, I do not agree that a comparison to [1] is impossible without their code. Instead, I'd encourage the authors to compare their method on the multi-MNIST benchmark described in Figure 1 [1] (and to just use the numbers provided by [1] for comparison without re-simulation). This would significantly strengthen the results. Unfortunately, however, I see two major flaws with the current presentation of the material: ** Literature and comparison to competitors First, the literature on this topic seems not to be suitably accounted for.
