NumpyNeuralNet

As the man himself said "What I cannot create, I do not understand.".
So I try to built Neural Networks and training algorithms using only Numpy.

Densely connected NN

Train a MNIST model with [output_activation]_[Loss].

• Sigmoid - MSE

  $ python test/dense.py sigmoid_mse train

• Sigmoid - Cross-entropy

  $ python test/dense.py sigmoid_crossentropy train

• Softmax - Log-likelihood

  $ python test/dense.py softmax_loglikelihood train
