  1. Artificial Intelligence ( AI ) AIT 600 Spring 08 Ahmed Ismail

  2. Overview

  3. What is the Artificial Intelligence? A.I. is the study of how to make computers do things at which, at the moment, people are better. AI is both the intelligence of machines and the branch of computer science which aims to create it.

  4. Actuator Sensor

  5. What’s involved in Intelligence? • Ability to interact with the world (speech, vision, motion, manipulation) • Ability to model the world and to reason about it • Ability to learn and to adapt

  6. AI Goals • To build systems that exhibit intelligent behavior • To understand intelligence in order to model it

  7. A Brief History of AI

  8. Computer Chess • 2/96: Kasparov vs Deep Blue • Kasparov victorious: 3 wins, 2 draws, 1 loss • 3/97: Kasparov vs Deeper Blue • First match won against world champion • 512 processors: 200 million chess positions per second

  9. Researcher tries to maximize the performance of the agents. • Just do it. • Computer scientists approach • Researcher tries to understand how the agents produce responses • Wait, let me figure what’s going on first • Psychologists approach

  10. Computer Chess • 2/96: Kasparov vs Deep Blue • Kasparov victorious: 3 wins, 2 draws, 1 loss • 3/97: Kasparov vs Deeper Blue • First match won against world champion • 512 processors: 200 million chess positions per second

  11. Robotics – Hopkins Beast 1964 Two versions of the Hopkins beast, which used sonar to guide it in the halls. Its goal was to find power outlets. http://www.frc.ri.cmu.edu/~hpm/book97/index.html

  12. Robotics – Stanford cart • 1971- Stanford cart. Remote controlled by person or computer. • 1971- follow the white line • 1975- drive in a straight line by tracking skyline • 1979- get through obstacle courses. Cross 30 meters in five hours, getting lost one time out of four http://www.frc.ri.cmu.edu/~hpm/book97/ch2/index.html

  13. Phil, the drug robot, introduced in 2003 Moving Around and Picking Things Up
