Presentation Transcript

  1. Artificial Intelligence AI: The branch of computer science dedicated to the creation of machines that perform task which if done by humans would be considered ‘intelligent’. Historical background Devices for aiding human mental processes trace back to earliest Egyptian and Mesopotamian civilizations 1600’s both William Schikard & Blaze Pascal developed calculating machines that could outperform humans 1800 Charles Babbage: difference engine and analytical engine 1930’s Allan Turing and the Turing Machine and the Turing Test 1940’s-50’s John von Neumann and the ‘von Neumann’ architecture – RAM; subroutines; serial processing

  2. Roman Abacus

  3. The Antikythera Calculator(Ancient Greek, 70BC)

  4. Schikard’s Adding Machine, 1623

  5. Blaze Pascal: Pascaline adding machine about 1650

  6. Charles Babbage: Analytical and Difference engines 1840’s

  7. Alan Turing: Turing test, Turing machine 1930’s

  8. John von Neumann and ENIAC 1942

  9. AI: Historical Background cont. • 1940’ McCullough and Pitts: neurons as logical operators • 1956: Birth of AI at MIT conference • AI camps: • GOFAI (symbol processors based on rules and information) • Rule following vs. common sense • Algorithms vs. pattern recognition/inference and meaning-making • Embodied AI (PDP models and robotics) • Expert systems (Narrowly designed AI for specific problems; e.g. EXCon for computer design; Mycin for medical diagnosis) • Philosophical issues: Is AI real intelligence? Searle’s “Chinese room” Principle of indistinquishibility Strong AI vs. weak AI

  10. Rodney Brooks and embodied AI

  11. Progress of computer chess champions: Ratings

  12. The triumph of Deep Blue • In 1996, Deep Blue vs. Garry Kasparov • DB 1 win; GK 3 wins; 2 draws. • In 1997, there was rematch. Result: 1 for GK; 2 for DB and 3 draws. • For the first time in history a computer was the world’s best chess player! • Deep Blue was a combination of special purpose hardware and software with an IBM RS/6000 SP2 (seen here) -- a system capable of examining 200 million moves per second, or 50 billion positions, in the three minutes allocated for a single move in a chess game.
