What is Artificial Intelligence?

Artificial Intelligence (AI) is
the attempt for computers to
perform intelligent actions.
According to John McCarthy,
AI is science and engineering
of making intelligent
machines, especially
intelligent computer
programs.

Brief History of AI

1950s – The Beginning of AI
* “Simon” by Edmund Berkeley created
* ”Computing Machinery & Intelligence” by Alan Turing
* John McCarthy coined the term “Artificial
Intelligence”
* First running AI program at CMU
* McCarthy creates LISP
History continued…

1960s and 1970s
* Danny Bobrow shows that computers can
understand natural language enough to solve
algebra word problems
* Joseph Weizenbaum builds ELIZA
* Shakey, a robot is created, which combines
locomotion, perception, and problem solving
* The first computer-controlled vehicle was built
History continued…

1980s and Early 1990s
* Danny Hills co-founds Thinking Machines
* The drawing program, Aaron, was created
* Major advances in all areas of AI, such as machine
learnng, intelligent tutoring, case-based reasoning,
multi-agent planning, scheduling, virtual reality, etc.
History continued…

Late 1990s and Today
* IBM computer Deep Blue beats the World Champion
chess player
* Web crawlers and other AI-based information
extraction programs became Web essentials
* Interactive robot pets become commercially
available
People That Have Influenced AI

Herbert Simon
* Father of modern research in AI
* Developed first AI software
*Computers stimulate human thinking

Allen Newell
*Unified Systems of Cognition
*SOAR
*Human problem solving
Herbert Simon
People continued…

John McCarthy
* Coined the term “Artificial Intelligence”
* Invented LISP

John McCarthy
Marvin Minsky
*The Society of the Mind
*Computers and human commonsense reasoning
People continued…

Alan Turing
* “Computing Machinery and Intelligence”
* The Turing Test
--http://www.AlanTuring.net

John Searle
Alan Turing
* Critique of computationalism and Strong AI
* Theory of intentionality
* Formed a naturalized theory of consciousness
Differences between Strong AI and
Weak AI

Strong AI
--Claims that computers can be made to think on a
level (at least) equal to humans and possibly even
be conscious of themselves

Weak AI
--States that some “thinking-like” features can be
added to computers to make them more useful tools
Aspects of AI

Fuzzy Logic
--Expresses operational laws of a system in linguistic
terms instead of mathematical equations

Moore’s Law
--The pace of microchip technology change is such
that the amount of data storage that a microchip can
hold doubles every year or at least every 18 months
Other Aspects of AI

Neural Networks
-- Systems that attempt to allow learning and to adapt
to different tasks that they are presented with

Robotics
--This field attempts to create robots that act
intelligently

Games
-- Good example of “Strong AI”
AI and Today


Machines doing the jobs of humans and animals.
Artificial Intelligence and the future.
