The Network is the outer container of all components. In normal use, it is the primary and only interface through which applications will interact. As you can see above, a Network is composed of Regions, which are in turn composed of Layers. The Layer being the unit of computation or processing as the figure above states.

To create a Network, you simply call the static factory method on Network like this:

Network.create("Optional Name", <Some Parameters>);

...as you can see, you can give it an optional name, and a set of Parameters. The same "Parameters" may be used at the Layer level also when creating Layers.
