Neural networks are automated structures, which are caused by the example of natural sensory chains that form (set up) the animal head. That sort of the structures study to complete the assignments, by looking through the samples, without being planned out.
NN comprise the series of the united elements or nodes named artificial neurons that easily imitate themselves in the organic substance. Each contact can transfer one signal from one AN to different ones. The imitation neuron that gets the indicators may convert it and gives signs to neurons united with it.
The signal in the contact among neurons may be a real sum. The finished product is generated by the set of the non-continuous functions of some original material. The layers are the basement of the artificial neurons.
