Hierarchical Graph Representation Learning with Differentiable Pooling

Recommendable! Well written paper! 

Two things that surprised me:

1. The researchers used the COLLAB dataset to exemplify some of the results although it has only a single level cluster structure ("This is because many collaboration graphs in COLLAB show only single-layer community structures, which can be captured well with pre-computed graph clustering algorithm"). Given that the researchers used so several other chemical and social network datasets.
2. The researchers used only maximal two DiffPool layers for all experiments
