artificial neural network

artificial neural network (artificial neural net) A computing system built from a large number of simple processing elements dealing individually with parts of a large problem. The net may have several layers of processing elements and the processing elements are massively interconnected. Adaptively adjusted weights are applied to the inputs and to the connections between the processing elements. There are many applications, including, for example, speech and pattern recognition, oil and gas exploration, financial forecasting, and health care cost reduction.
