2. 1.Artificial intelligence, simulation and modelling Human thought and interaction have been a dream for a long time. This has not eventuated. Computers are good at calculating and this power is used to simulate human interaction Pattern matching is used after a document has been scanned to identify characters. This is called OCR (Optical Character Recognition). Recent development have included face recognition in airports to identify criminals Language translation sites are becoming more useful and powerful Voice recognition used by computers has developed slowly with minimal use. An area of usage is call centre automation where the user attempts to ask for a service The Sims

3. 1.Continued… Expert systems are computer program that perform diagnostic functions. The are common in hospitals for diagnosing medical conditions. The are also used in Telstra to fault find network problems. Expert system use rules developed by experts. Neural networks use trial and error to guess outcomes. They operate similar to the human brain and are used to identify signatures and heart attack risk

4. 2.Class Task Research and describe in one paragraph an example of an ‘expert system’ (rules set by a SME Subject matter Expert) and a ‘neural network’ Examples may come from industries such as Defence Mobile phone engineering Automotive engine management system Rail network planning Real estate Airport scheduling Gaming Share market trading Medical diagnostics
