Artificial Neural Network (ANN for short) is a processing model inspired on the biological neural networks. Artificial neural networks are composed by simple nodes called artificial neurons and the processing behavior is stored in the node interconnections as weights.
Adaptation and Learning
When a neuron receives and processes an input signal, it changes its behavior by changing its threshold and/or weight values, modifying the network. Since artificial neurons have a predictable behavior, artificial neural networks can be trained by being fed with sequences of inputs, often determined by certain functions which are parts of several algorithms. Besides, there are neural networks which do not require training.
