Wasserstein Loss Layer

Implements the Wasserstein Loss Layer (as described in Frogner et al. 2015) in Caffe. (Previously, the only open source implementation of the loss function was in Mocha.jl, which we used as a reference)

Project Report

Check ./project.pdf

Example Models using the loss layer

Check ./examples/mnist and ./examples/sample_wasserstein

TODO

Fix the test to check for difference in gradient.
