Unsupervised Neural networks A neural network is a system composed of many simple processing elements operating in parallel whose function is determined by network structure, connection strengths, and the processing performed at computing elements or nodes. Neural networks are commonly known as "artificial neural network" (ANN). An Artificial Neural Network (ANN) is an information-processing system that is evolved by the way biological nervous systems works, such as the human brain. Neural networks have broad applicability to real world business problems. In fact, they have already been successfully applied in many industries. Since neural networks are best at identifying patterns or trends in data, they are well suited for prediction or forecasting needs including: Sales forecasting Industrial process control Customer research Data validation Risk management Target marketing These neural networks are also used in the following specific paradigms: recognition of speaker s in communications; diagnosis of hepatitis; recovery of telecommunications from faulty software; inte...
