3  What is INTELLIGENCE? › Ability to reason › Ability to acquire and use knowledge › Ability to perceive ideas › Ability to manipulate objects  What is AI? › Ability of computers to imitate human behaviour and thought processes. Information and Software Technology

5  Ancient Greek philosopher Aristotle (384 – 322BC) logical reasoning form the basis of many AI systems. Aristotle Info Aristotle Info Information and Software Technology

6  Alan Turing (1912 – 1954) created the Turing machine that could perform logical operations.  The Turing test is where a human has to determine if the response was generated by a computer or a human.  Who Was Alan Turing Who Was Alan Turing Who Was Alan Turing  The Enigma The Enigma The Enigma Information and Software Technology

7  The Future? The Future? The Future?  Would you like to know more?   HW Page 169 Exercise 8.1 q’s Information and Software Technology

8  Major areas of AI › Intelligent Systems › Expert systems and Knowledge Bases › Neural networks › Games › Natural language › Robotics  DVC “I,video” Information and Software Technology

11  An Artificial Intelligent system is a computer system that receives data through an input device such as a mouse, keyboard or microphone and produces an intelligent response.  Can you find one on the Internet and paste the link into Wallwisher! Information and Software Technology

12  Expert systems are computer programs that make the collective knowledge of various experts in a field available to the user. They are built on knowledge bases. Information and Software Technology

13  Examples of expert system include › Medical expert system › Voice recognition system › Travel navigation expert system › Financial systems Information and Software Technology

14  Expert System Example Expert System Example Expert System Example  Investigate an expert system.  place your findings on our Wallwisher site. Information and Software Technology

15  Create a PREZI on something to do with AI (can not be a movie)  Include pictures and video.  Present a 5 Minute PREZI to the class. Information and Software Technology

16  A computer system that works like the human brain and is capable of learning.  Watch video Watch video Watch video Information and Software Technology

17  Knowledge bases – a centralised repository for information. Computers can be programmed to use rules based on set conditions. IF-THEN rule. › IF this knowledge exists (premise) THEN do this (conclusion). Information and Software Technology

18  Agents – A piece of software designed to search through databases for relevant data. Used in neural networks to search vast amounts of data. Information and Software Technology

19  Demons – A program that springs to life when it is relevant. Allow computers to be self-modifying.  HW Page 175 Exercise 8.2 q’s 1-4 Information and Software Technology

20  Model – a simpler version of a real world object or idea.  Modelling – process of creating a model. Information and Software Technology

21  Computer model – an electronic representation of an object or idea.  Simulation – the process of imitating real-life occurrences in order to test a model. Information and Software Technology

22  Spreadsheets Spreadsheets  Financial Planners Financial Planners Financial Planners  Car Manufacturers Car Manufacturers Car Manufacturers  Training Simulators Training Simulators Training Simulators  Drilling Simulators Drilling Simulators Drilling Simulators  Space Shuttle Missions Space Shuttle Missions Space Shuttle Missions  Scientific Simulations Scientific Simulations Scientific Simulations  Astronomers Astronomers Information and Software Technology

23  Safer, cheaper and quicker to use a model.  More efficient and minor changes to the models can be easily altered.  Life Like????? Life Like????? Life Like????? Information and Software Technology

24  Might be the only method for training (astronauts).  The simulation is only as good as the model that was created. Information and Software Technology

25  Models are often too simplistic and lead to inaccurate results.  HW Page 178 Exercise 8.3 q’s 1- 4 Information and Software Technology

26  Hardware Hardware › Can take a lot of time to build the required hardware. › The hardware needs fast processing › Parallel processing (linking of two or more processing units within the one computer) is often used. › Large amounts of storage space is required. Information and Software Technology

27  Software › Required to carry out complex computations. › Specifically designed to suit the model. Information and Software Technology

28  A hardware device that imitates certain environments. Used for training and experiments to simulate movement. Information and Software Technology

29  Flight simulators › Used to train pilots and provide realistic feelings of flying › Has working replica of cockpit, computers, projectors and screens. Information and Software Technology

30  Car simulators › Good for learner drivers.  Virtual reality games › Users usually wear a head-mounted display that presents computer images to each eye and sounds through earphones. Homework Exercise 8.4 q’s Information and Software Technology
