WHAT IS ARTIFICIAL INTELLIGENCE ?

Artificial intelligence
(AI) is the intelligence of
machines
and
the branch of computer science.

John McCarthy
(September 4, 1927


October 24, 2011)
was an American computer scientist. He invented the
term

Artificial
I
ntelligence
" (AI) and he defines it as
‘’The
Science
and
Engineering
of making intelligent
machines ‘’



WHAT IS EXPERT SYSTEMS ?


Expert

System

is an
Artificial

intelligence

based system
that converts the knowledge of an expert in a specific
subject into a software code.

Expert Systems
are designed to solve complex problems
by reasoning about knowledge, like an expert, and not
by following the procedure of a developer as is the case
in conventional
programming.

WHAT IS EXPERT SYSTEMS ?



The
first
Expert Systems
were created in the
1970
s and then upgraded in the
1980
s.


Expert Systems
were among the first truly
successful forms of
AI

software.


HOW DO EXPERT SYSTEMS
WORK ?

An expert system is made up of
three

parts:

1.
A user interface
:

This
is the system that allows a non
-
expert user to query
(question) the
expert
system, and to receive advice.

2.
A knowledge base
:


This is a collection of facts and rules. The knowledge
base is created from information provided by human
experts.


HOW DO EXPERT SYSTEMS WORK ?

3.
An inference engine
:

This
acts rather like a search engine, examining the
knowledge base for information that matches the user's
query.


WHAT ARE THE APPLICATIONS ?

Expert

Systems

are usually used in:


Medical

Diagnoses
;


Playing

Strategy Game like
Chess Against
PC
;


Financial

Advice

whether to invest in a
business or not..;

WHAT ARE THE APPLICATIONS ?

Medical

Diagnosis

:

The
knowledge base would contain medical
information, the symptoms of the patient
would be used as the query, and the advice
would be a diagnose of the patient’s
illness.

WHAT ARE THE APPLICATIONS ?

Playing

Chess :

Playing strategy games like chess against a
computer
, the
knowledge base would contain
strategies and moves, the player's moves
would be used as the query, and the output
would be the computer's

Expert
” moves.

WHAT ARE THE APPLICATIONS ?

Providing
financial

Advice

:

W
hether
to invest in a business, etc. T
he
knowledge base would contain data about the
performance of financial markets and
businesses in the
past.

WHAT IS THE
FUTURE

OF EXPERT SYSTEM
?

In the next 10 years technologies in narrow fields such
as speech recognition will continue to improve and
will reach human levels. In 10 years AI will be able to
communicate with humans in unstructured English
using text or
voice
.



WHAT IS THE
FUTURE

OF EXPERT SYSTEM ?

We will recreate some parts of the human
(animal) brain in silicon. The feasibility of
this is demonstrated by tentative
hippocampus experiments in rats . There are
two major projects aiming for human brain
simulation,
CCortex

and IBM Blue Brain.



WHAT IS THE
FUTURE

OF EXPERT SYSTEM ?

There will be an increasing number of practical
applications based on digitally recreated
aspects human intelligence, such as cognition,
perception, rehearsal learning, or learning by
repetitive practice.
