What is Artificial Intelligence? Abbas Mehrabian Teacher: Dr. M. Raei Sharif Saturday, 6 Esfand 1384

I will not talk about Robots!

What is Intelligence and who is Intelligent?

About Intelligence  Intelligence is subjective, –You need not be great in all domains to be called intelligent. –Physicists boil watches!  Intelligence is a relative measure. –A very small child who talks easily –A dog which identifies his owner’s voice

What do they say about Intelligence?  Intelligence is the ability to carry out abstract thinking.  Intelligence is adaptation to the environment.  Intelligence is what you do when you don't know what to do.

What is ARTIFICIAL Intelligence? Samples  Thermostats?  Computers that switch to “stand by” mode automatically?  Phones that recognize names?  Airplanes autopilots?

What are the goals of Artificial Intelligence?  To create machines, that can do more jobs than previous ones, with better performance.  To add features to machines which machines don’t have, but human has. –Human can conclude from known facts. –Human can guess! –Human can make relations between new un- identified objects and known objects.

Why are Humans Intelligence?  Learning  Reasoning  Problem Solving  Feeling environment –Vision (being able to recognize object by seeing) –Audio (being able to recognize voices)

Formal Definition of ARTIFICIAL INTELLIGENCE Human Level logic + emotion Logical Behavior Systems that behave like humans. Systems that act logically. Thinking Systems that think like humans. Systems that think logically.

How to Judge A.I.?  Systems that act like human. –Turing Test, Alan Turing, 1950  Basic test: –Judge (human) in one room, human in another, system in a third –Judge asks questions; human and system answer –Judge tries to guess which is which –If the system wins, it’s passed the Turing Test and it is intelligence!

The abilities a system should have to pass the test  Natural Language Processing  Knowledge Representation  Reasoning  Learning

When Philosophy interacts with AI….  CAN MACHINES THINK? –Can: now or future? Maybe we need more advanced technology –Machine: Is human a protein machine? –Think: Does the intelligent system “knows” what it does? Engineering view: It’s not important! Machines can help us in industry…and that’s enough!
