Discussion on: Build a flexible Neural Network with Backpropagation in Python

Nice guide. I have one question:

Shouldn't the input to the NN be a vector? Right now the NN is receiving the whole training matrix as its input. The network has two input neurons so I can't see why we wouldn't pass it some vector of the training data.

Tried googling this but couldnt find anything useful so would really appreciate your response!

I am not a python expert but it is probably usage of famous vectorized operations ;)
