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 unidentified 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
Logical
logic + emotion
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!
