Alan Turning is considered as the father
of Artificial Intelligence. The other
pioneers in the field of AI are John
McCarthy, D.Lenat, Alan Maurveraur and
others.Artificial intelligence is the part of
computer science concerned with
designing intelligent computer system that
is systems which exhibit the characteristics
we associate with intelligence in humans.
It deals with symbolic ,non-algorithmic methods of
Neural Network and Artificial
Neural networks, as used in artificial
intelligence, have traditionally been viewed
as simplified models of neural processing in
A subject of current research in
theoretical neuroscience is the question
surrounding the degree of complexity and
the properties that individual neural
elements should have to reproduce
something resembling animal intelligence.
Fuzzy logic is a form of multi-valued
logic derived from fuzzy set theory to
deal with reasoning that is approximate
rather than precise. Just as in fuzzy set
theory the set membership value is in
range of 0 to 1, in fuzzy logic the degree
of truth of a statement can range
between 0 and 1 and is not constrained
as in classic predicate logic.
When linguistic variables are used,
these degrees may be managed by some
Characteristics of AI
Deduction, reasoning, problem solving
Early AI researchers developed
algorithms that imitated the process
of conscious, step-by-step reasoning
that human beings use when they solve
puzzles, play board games, or make
By the late 80s and 90s, AI research had also
developed highly successful methods for dealing
with uncertain or incomplete information,
employing concepts from probability and
Knowledge representation and
knowledge engineering are central to AI
research. Many of the problems
machines are expected to solve will
require extensive knowledge about
Among the things that AI needs to
represent are: objects, properties,
categories and relations between
objects; situations, events, states and
time; causes and effects; and many
other, less well researched domains.
Intelligent agents must be able to set
goals and achieve them. They need a way
to visualize the future and be able to
make choices that maximize the utility of
the available choices.
The idea behind machine learning is
primarily concerned with the study and
development of programs which learn
from their experience
Natural language processing
Natural language processing gives
machines the ability to read and
understand the languages human
Many researchers hope that such
system would be able to acquire
knowledge on its own, by reading the
existing text available over the
Some straight-forward applications
include information retrieval and
Perception is the ability to use input
from sensors to deduce aspects of the
Computer vision is the ability to analyze
visual input. A few selected subproblems
are speech recognition, facial recognition
and object recognition
Motion and Manipulation
The field of robotics is closely related to
AI. Intelligence is required for robots to
be able to handle such tasks as object
manipulation and navigation.
Genetic Algorithm (GA)
A genetic algorithm (GA) is a search
technique used in computing to find
exact or approximate solutions to
optimization and search problems.
Genetic algorithms are categorized as
global search heuristics.
Genetic algorithms are a particular
class of evolutionary algorithms that
use techniques inspired by evolution
-ary biology such as inheritance,
mutation, selection, and crossover .
APPLICATIONS OF AI
Financial institutions have long used
artificial neural network systems to detect
charges or claims outside of the norm,
flagging these for human investigation.
Robots have proven effective in jobs that
are very repetitive which may lead to
mistakes or accidents due to a lapse in
concentration and other jobs which humans
may find degrading
Of all the application of artificial
intelligence , expert systems are perhaps
the most familiar and are certainly the
most commercially successful.
An expert system is basically an AI
program which uses knowledge to solve
the problems which would normally
required a human expert.
The system includes a reasoning
mechanism for making choices and
navigating around the search space for
A medical clinic can use artificial
intelligence systems to organize bed
schedules, make a staff rotation, and
provide medical information.
Artificial neural networks are used for
medical diagnosis (such as in Concept
Processing technology in EMR
software), functioning as machine
The Air Operations Division , AOD, uses for the rule
based expert systems
Fuzzy logic controllers have been
developed for automatic gearboxes in
automobiles (the Audi TT, which
utilizes Fuzzy logic, a number of
Skoda variants also currently include a
Fuzzy Logic based controller).
Many telecommunications companies
make use of heuristic search in the
management of their workforces, for
example BT Group has deployed
heuristic search in a scheduling
Toys and games
Artificial Intelligence for education,
or leisure. This prospered greatly with
the Digital Revolution, and helped
introduce people, especially children,
to a life of dealing with various types
of AI, specifically in the form of
Giga Pets, the Internet , and the first
widely released robot, Furby.
A mere year later an improved type
of domestic robot was released in the
form of Aibo, a robotic dog with
intelligent features and autonomy.
The Main AI Languages
The main programming languages used in AI are
Lisp and Prolog. Both have features which make them
suitable for AI programming, such as support for list
processing, pattern matching and exploratory
LISP uses the list as its fundamental representation
for data structures and programs (function definitions),
and provides a wide range of built in functions for
PROLOG is a language based on logic. In particular,
it is based on first order predicate calculus
It can be concluded that in spite of impressive
achievements , on the hardware and software fronts it
has not been possible to produce coordinated
autonomous system which possess some of the basic
abilities of a three year old child.
Information creation, Autonomy, Situated ness
can be regarded as focuses for the AI research and
development in future. In order to come up to these
challenges, a lot of single methods have to be
integrated into greater systems.
