Who is Intelligent? And why?

Intelligence

Knowledge Logical Reasonable Or just Human?

Artificial Intelligence

Designing machines that: Think like

human Act like human Think Rationally Act Rationally

Being rational means maximally achieving your pre-defined goals

Why not mimic human brain?

“Brains are to Intelligence as wings are to flight”

Brains are good at rational thinking but not perfect

The Turing Test

Footprints of AI

Dates back to 8th century BC, greek mythology. Hephaestus created Talos to guard crete.

Footprints of AI Aristotle 4th century BC, developed an

informal logic system Descartes, 17th century AD proposed animal

bodies are complex machines Blaise Pascal, 1642, first mechanical digital

calculator 19th century, George Boole developed binary

algebra better known as boolean algebra Charles Babbage worked on programmable

calculators

Footprints of AI 1943, McCulloch & Pitts: Boolean circuit model of

brain 1950, Alan Turing published “Computing Machinery

and Intelligence” introduced concept of learning in machines by letting them alter their program

1950s, Samuel's checkers program, Newell & Simon's Logic Theorist, Gelernter's Geometry Engine

1956: Dartmouth meeting: the term “Artificial Intelligence” adopted

1965: Robinson's complete algorithm for logical reasoning

Footprints of AI 1980-88: Expert systems industry

booms 1988-93: Expert systems industry busts:

“AI Winter” 1990s: Resurgence of probability, focus

on uncertainty Neural Networks became more popular,

Agents and learning systems bloomed 1997, Deep Blue beats Gary Kasparov

What AI can and cannot Play sports like soccer/Table tennis? Play a decent game of Jeopardy? Drive safely along a curving mountain road? Buy a week's worth of groceries on the web? Discover and prove a new mathematical theorem? Converse successfully with another person for an hour? Perform a surgical operation? Put away the dishes and fold the laundry? Translate spoken Chinese into spoken English in real

time? Write an intentionally funny story? Understand human emotions and imitate them?

What AI can and cannot Detect cancer? Plan a journey to Andromeda

galaxy? Surf the internet? Create aesthetic music? Write a creative poetry?
