Expert Systems o Rely on obtaining the knowledge of human experts and programming that knowledge into a system o Diagnostic systems o Financial decision making o Classification systems

Diagnostic systems MYCIN system for diagnosing bacterial infections of the blood and suggesting treatments. l Intellipathology diagnosis system (AMA approved). l Pathfinder medical diagnosis system, which suggests tests and makes diagnoses. l Whirlpool customer assistance center. l

Financial decision making l Credit card companies, banks, and the U. S. government employ AI systems to detect fraud and expedite financial transactions. For example, AMEX credit check. Systems often use learning algorithms to construct profiles of customer usage patterns, and then use these profiles to detect unusual patterns and take appropriate action.

Classification Systems l Put information into one of a fixed set of categories using several sources of information. E. g. , financial decision making systems. NASA developed a system for classifying very faint areas in astronomical images into either stars or galaxies with very high accuracy by learning from human experts' classifications.

Biology & Medicine o Diagnosis systems o Specialists often use statistical AI tools to diagnose a patient has a disease based on his/her symptoms

Machine Learning o Automated Mathematician, designed to discover mathematical laws.
