Conclusion
It might be me, but I was missing a section on possible future directions and the drawbacks of using this model. Noticed that there was a lot of praise, but couldn't find a lot of critiques. (Or I might overseen it as I'm writing this at half 4 in the morning.)
Normally, you could find the published reviews on OpenReview with the discussed critique (see: https://papers.nips.cc/paper/2016/file/fb87582825f9d28a8d42c5e5e5e8b23d-Reviews.html which I used for another repro course), but when googling on this paper, I couldn't find it :(
Either way, here's the OR link to the current paperhttps://openreview.net/forum?id=FOL6UA7JYtk)
