MNIST and noMNIST - Theano and tensorflow

I warmly recommend Alec Radford's Theano-Tutorials to anyone interested in ML and Theano. His bare-bones approach yields remarkable clarity and effectiveness. I have adapted Alec's convolutional_net so that it works both with the MNIST dataset and on the noMNIST dataset used in the officoal tensorflow tutorial. The result is a remarkable 97.5% accuracy for the latter. To check it out you will have to build noMNIST.pickle and then place it in the data directory.  Besides,  comparing Theano and tensorflow may help understand each better.
