The use of neural networks in R with neuralnet package.

As the computing power grows the implementation of Artificial Neural Networks (ANN) becomes more and more common in computational systems and programs. Here it is explained what a simple feedforward artificial neural network is and how it is supposed to work.  This article is a demonstration about the R library neuralnet [1a,b] and how it can be applied.

Neural Networks (a brief intro)

Artificial Inteligence was a known term and describes the concept of how a machine can learn and addapt from/to situations.
