I will take it out. I would like to note that this cost doesn't match up with the paper (at least if I am reading the paper right). However, I couldn't get the version from the paper to work, which is the commented out version. I did find this version, from [here](http://nbviewer.ipython.org/urls/raw2.github.com/breze-no-salt/breze/master/notebooks/Charlie%20Tang's%20Deep%20Network%20with%20SVM%20Loss%20on%20MNIST.ipynb?create=1)
