Camera-ready submission

This is the version of the code used for all the revised experiments in the camera-ready paper.

Accompanying this release will be the experiment logs, pre-processed data, and data splits of the paper.

One (and maybe the only) substantial difference between the architecture submitted for the initial submission and this one, is the use of rmsprop as the optimizer, instead of adam.

I found that rmsprop was generally better and decided to use it as the default.

Every revised experiment in the camera-ready paper uses rmsprop. As observed before, the results went slightly above just because of that.
