Abstract:

Artificial Neural Network is a math model which is applied to process information of the structure which is similar to Brain synaptic connection in a distributed and parallel way. Artificial Neural Network is a computing model, and it contains of many neurons and the connection of the neurons. Every neuron represents a special output function which is called activation function. The connection of neurons represents a weighted value of the connection’s signal.

Neuron is a basic and essential part of Artificial Neural Network, and it includes the sum of weighted value, single-input single-output (SISO) system and nonlinear function mapping. The element of neuron can represent different thing, such as feature, alphabet, conception and some meaningful abstract pattern. In the network, the style of neuron’s element divided into three categories: input element, output element and hidden element. The input element accepts the signal and data of outer world; the output element processes result output for system; the hidden element cannot find by outer world, it between input element and output element. The weighted value represents the strength of connection between neurons.

Artificial Neural Network adopted the mechanisms that completely different from traditional artificial intelligence and information processing technology. It conquers the flaw of traditional artificial intelligence in Intuitive handling and unstructured information processing aspect. It is adaptive, self-organized and learning timely, and widely used in schematic identification signal processing.
