Artificial Neural Network

AI-LogoComputer-based neural networks are capable of “learning” how to model the behavior of the brain –- including recognizing objects, characters, voices and audio in the same way that humans do.Artificial intelligence (AI) refers to computer software that exhibits intelligent behavior. The term “intelligence” is difficult to define, and has been the subject of heated debate by philosophers, educators, and psychologists for ages. Nevertheless, it is possible to enumerate many important characteristics of intelligent behavior.

Neural networks have received a lot of attention for their abilities to ‘learn’ relationships among variables. They represent an innovative technique for model fitting that doesn’t rely on conventional assumptions necessary for standard models and they can also quite effectively handle multivariate response data.
Neural Networks
Neural networks simulate the human nervous system. The concepts that guide neural network research and practice stem from studies of biological systems. These systems model the interaction between nerve cells. Components of a neural network include neurons (sometimes called “processing elements”), input lines to the neurons (called dendrites), and output lines from the neurons (called axons).

There are many types of artificial neural networks (ANN). An artificial neural network  is a computational simulation of a biological neural network. These models mimic the real life behaviour of neurons and the electrical messages they produce between input (such as from the eyes or nerve endings in the hand), processing by the brain and the final output from the brain (such as reacting to light or from sensing touch or heat). There are other ANNs which are adaptive systems used to model things such as environments and population.
