If you need direct access to the weights, the best method is to use BasicNetwork.GetWeight(). Here is an example that shows how to use GetWeight to obtain all of the weights in the neural network. It is from a unit test, to prove that GetWeight does work, it calculates the...

You should take a look at some of the tutorials over at deeplearning.net. They have a Stacked Denoising Autoencoder example with code. All of the tutorials are written in Theano which is a scientific computing library that will generate GPU code for you. Here's an example of a visualization of...
