I'm really surprised at how fast the first attempt went.  I thought I would struggle a bit more because of all the details I don't know.  Sure, I know that there are layers and some are hidden.  I know that you can have different kinds of layers Sigmoid and Tanh, but I don't know the difference yet.  In spite of what I don't know, I was still able to follow the very simplistic tutorial.

Step One: Start Python

Step Two: Import pybrain and create a network.

With a network that has 3 hidden layers, 2 inputs, and 1 output neuron, would you believe that the next step is the neural network equivalent of a "Hello World" program?  The modules are already connected and ready to do something.

Step Three: Activate the Network

Done.  What do those numbers mean?  Nothing.  We didn't use any training data and nothing is truly ready, but just as in a "Hello World" tutorial, this is just to show that something has been accomplished.  There is so much more to the subject, but until I read some books on deep learning, I think I've reached the end of what I can do without knowledge.  It's a fun first step. 

I'm sure someone or some book once told me what the array of strings passed into the main method of a Hello World application was for.  I'm equally sure it never mattered to me.  To be honest, it still doesn't, but let's talk about it for a second.

​

The above application is a very traditional style of hello world application.  It's done this way so you don't have to ask more questions than necessary.  But there's parts of this application that I never questioned.  The code below gives us a glimpse at what the string array is doing.

This slightly different implementation allows me to pass two strings into the application when I call it and it will output those strings with a space in the middle.

This means that this could be a Happy Birthday application without making any changes to it. You would simply pass in Happy and Birthday when you execute the app.  Because this isn't a groundbreaking discovery, there's nothing more about this to discuss.  Just remember that if you want to pass any arguments to your application, you can.
