Neural Network
A neural network made up of layers of neurons connected to each other to form a relationship allowing it to learn. This network is still a work in progress but is far enough along to get an idea of how it works. This is a reimplementation of what was started here: https://github.com/kblake/neural-net-elixir-v1.
After cloning:
$ mix compile
Usage
Run the trainer and see the network learn using OR GATE data
$ mix learn or
You should see output like this:
