 In this repo you will find a set of functions that allow you build a neural network, to regression or clasiffication problemas, using
 the brack propagation algorithm and the sigmoid function as the activation function.
 
-The structures and functions developed are all fully parametrized so you can desing your own neuarl network architecture, and implement other activation function and use them easily.
