2. Today we’ll discus:
• Intelligence
• Artificial Intelligence
• A brief history of AI
• Cool current projects in AI
3. 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
4. Goals in AI
• To build systems that exhibit intelligent
behavior
• To understand intelligence in order to
model it
6. A Brief History of AI
• 1943: McCulloch and Pitts propose a model
of artificial neurons
• 1956 Minsky and Edmonds build first
neural network computer, the SNARC
7. The Dartmouth Conference
(1956)
• John McCarthy organizes a two-month
workshop for researchers interested in
neural networks and the study of
intelligence
• Agreement to adopt a new name for this
field of study: Artificial Intelligence
9. 1966-1974 Reality:
• AI problems appear to be too big and
complex
• Computers are very slow, very expensive,
and have very little memory (compared to
today)
11. 1980-1988 AI in industry:
• R1 becomes first successful commercial
expert system
• Some interesting phone company systems
for diagnosing failures of telephone service
12. 1990s to the present:
• Increases in computational power
(computers are cheaper, faster, and have
tons more memory than they used to)
• An example of the coolness of speed:
Computer Chess
13. 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
How do you think it works???
