Neural Networking is a computing science field that is not so well known among most software developers, but it can help solving problems that are difficult to solve with conventional computing methods. Neural Networking consists of emulating the way a brain works by the means of networks of interconnected neurons. These neurons have inputs and outputs. They receive input signals that are combined according to some internal factors to define their output signals. The neural networks need to be trained to perform some useful tasks. Usually these tasks consist of perceiving patterns in the input signals of their neurons. This is why they are also known as perceptrons. Training consist of submitting a reasonably large sample of subjects that need to be recognized. Iteratively the values of internal factors of each neuron are adjusted until they output the desired response with an acceptable error rate. The most common applications of neural networks are usually recognizing patterns that otherwise would be hard to distinguish by common computing methods, like for instance, recognizing handwritten characters in a scanned image. This class provides an implementation of a perceptron. It comes with an example application of classifying users by type of profile based on the answers that they provide to questions presented in a Web form. Since the class provides a generic implementation of a perceptron, there could be many other examples of application for this class, possibly only limited by the imagination of the developers that understand its potential.
