Neural Network, is a computer program and data structures that operates similar to the human brain. The main appeal of neural networks is their ability to follow the brain’s pattern-recognition skills. usually involves a large number of processors operating in parallel, each with its own small field of knowledge and access to data in its internal memory. In general, a Neural Network is primarily fed large amounts of data and rules about data interactions. with commercial applications of this ability, Neural Networks have been used to recognize handwriting, make investment decisions, and even detect illness. Many banks and financial company use Neural Networks, to study potential financial markets opportunities. In addition, Neural Networks are used in fraud detection. Visa, MasterCard, and many other credit card companies use a neural network to maintain client accounts. “MasterCard estimates Neural Networks save them $50 million annually”.

Expert systems are computer applications that consist of; computer equipment, software, and specialized information to emulate expert human interpretation and advice. As a branch of artificial intelligence, Expert systems provide specific advice and explanation to their users. While artificial intelligence is a wide field dealing with many portions of computer thought, Expert systems are more narrowly focused. in general, Expert systems function best with specific activities or problems. Expert systems are used widely in commercial and industrial services, including medicine, finance, manufacturing, and sales. Easydiagnosis.com offers an excellent example of Expert systems, that their expert system software provides a medical description and directory for the most possible situation based on an analysis of client symptoms. “Easydiagnosis focuses on the most common medical complaints that account for the majority of physician visits and hospitalizations”. http://easydiagnosis.com/.
