Welcome, This is my implementation multilayer Neural Network created using only the python's numpy package. It's based on the Neural Network from the book Neural Networks and Deep Learning by Michael Nielsen. I recommend reading that if you want to learn more.
First make sure you numpy installed.
$ git clone https://github.com/vedantrathore/digits-recognition.git
$ cd digits-recognition/
$ wget "https://raw.githubusercontent.com/mnielsen/neural-networks-and-deep-learning/master/data/mnist.pkl.gz"
$ python network.py
This is was inspired from this repository and uses some of it's code.
