DS: Microsoft Office Assistant in Office 97 provides customized help by decision-theoretic reasoning about an
individual user. MYCIN system for diagnosing bacterial infections of the blood and suggesting treatments.
Intellipath pathology diagnosis system (AMA approved). Pathfinder medical diagnosis system, which
suggests tests and makes diagnoses. Whirlpool customer assistance center.
SC: DEC's XCON system for custom hardware configuration. Radiotherapy treatment planning.
FDM: Credit card companies, mortgage 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.
CS: 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.
