3. exhibited several characteristics HAL in 2001: A Computer with Artificial Intelligence In 2001: A Space Odyssey (book by Arthur Clarke, movie by Stanley Kubrick, 1968), the HAL 9000 computer onboard the spacecraft exhibited several characteristics which represent areas of artificial intelligence research today: Capacity to understand natural languages: natural language processing. Capacity to understand natural languages: natural language processing. Facility with logic: expert systems and logic programs. Facility with logic: expert systems and logic programs. Visual ability to understand what it is seeing: neural networks for image processing. Visual ability to understand what it is seeing: neural networks for image processing. Capability to monitor and control the spaceship: robotics. Capability to monitor and control the spaceship: robotics. We will discuss them, but let us start from the beginning…...

5. Autonomous robot needs Artificial Intelligence Autonomous robot needs Artificial Intelligence

7. What is AI?

8. How do we classify research as AI?

Synonyms: Synonyms:  Brain, brainpower, mentality, mother wit, sense, wit Related: Related:  Acumen, discernment, insight, judgment, perspicacity, sagacity, wisdom

10. Definition of AI (first try) Artificial Intelligence is the enterprise of constructing an intelligent artifact Artificial Intelligence is the enterprise of constructing an intelligent artifact

11. Intelligence What is intelligence? What is intelligence? Doing what people do? Doing what people do?  vision  voice recognition  game playing  people solve many subtle problems Current programs are brittle Current programs are brittle

12. Alan M. Turing Computing Machinery and Intelligence Turing Test Thirty minutes to ask questions If you cannot distinguish between a person and the artificial system based on the responses, then the system is intelligent (how many tries, language,etc)

13. Intelligence Turing Test: A human communicates with a computer via a teletype. If the human can’t tell he is talking to a computer or another human, it passes. Turing Test: A human communicates with a computer via a teletype. If the human can’t tell he is talking to a computer or another human, it passes.  Natural language processing  knowledge representation  automated reasoning  machine learning Add vision and robotics to get the total Turing test. Add vision and robotics to get the total Turing test.

14. The Imitation Game If a computer can “fool” a human interrogator into believing that it is human, then it may be said that the machine is intelligent, and thinks. The scope of questions that may be asked is virtually unlimited. The imitation game competition

15. Example of an Interrogation Q: Please write me a sonnet on the subject of the Forth Bridge. A: Count me out of this one. I never could write poetry. Q: Add 34957 to 70764. A: 105621. Q: Do you play chess? A: Yes. Q: I have K at my K1, and no other pieces. You have only K at K6 and R at R1. It is your move. What do you play? A: R-R8 mate.

16. One more definition of Turing Test

17. A Refined Definition Artificial Intelligence is the enterprise of constructing an artifact that can reliably pass the Turing Test Artificial Intelligence is the enterprise of constructing an artifact that can reliably pass the Turing Test

18. Objections to the Turing Test Not everything about human can be learned by only talking by phone Not everything about human can be learned by only talking by phone Is looking an answer up in a large table really intelligence? Is looking an answer up in a large table really intelligence? Does a functional definition of intelligence really characterize human intelligence? Does a functional definition of intelligence really characterize human intelligence?

19. What are artifacts? What are artifacts? points to discuss An inorganic object An inorganic object A physical-symbol system A physical-symbol system symbols symbols expressions expressions a symbol manipulating entity a symbol manipulating entity symbols correspond to objects in an environment symbols correspond to objects in an environment

20. A Final Definition Artificial Intelligence is the enterprise of constructing a physical symbol system (a robot) that can reliably pass the Turing Test Artificial Intelligence is the enterprise of constructing a physical symbol system (a robot) that can reliably pass the Turing Test

21. Weak and Strong AI Claims Weak AI: Weak AI:  Machines can be made to act as if they were intelligent. Strong AI: Strong AI:  Machines that act intelligently have real, conscious minds.

29. Your task What is your definition of intelligence? What is your definition of intelligence?  Can your definition be applied to a robot? Give one example from your area what is “Knowledge”. Give one example from your area what is “Knowledge”.  How this knowledge can be represented in LISP? Give one example from your area what is “Representation” Give one example from your area what is “Representation”  How your representation will be implemented in LISP? Give an Example of a Turing test limited to some area, in which it will be relatively easy but not trivial for a machine to pass. For instance, if you restrict the test to questions about baseball league.
