Introduction


AI is a branch of Computer
Science concerned with
the study and creation of
computer systems.
AI exhibits some form of
intelligence:
– systems that learn new
concepts and tasks,
– can reason and draw
useful conclusions
about the world.

AI systems also
can understand a
natural language
or perceive and
comprehend a
visual scene, and
perform other
types of feats that
require human
types of
intelligence.
Introduction (counted.)
PERCEPTS
SENSORS
ENVIRONMENT
AGENT
ACTIONS
EFFECTORS
Figure . Agents interact with environments through sensors
and effectors
History
1940 - 1950; knowledge of the basic
physiology and function of neurons in
the brain.
 Revolutions have occurred in robotics,
computer vision, machine learning
(including neural networks) and
knowledge representation.

AI performances




Knowledge representation is a design for knowledge–
based agent.
Expert systems are programs that mimic the behavior of
a human expert. They use information that the user
supplies to sender an opinion on a certain subject. The
expert system asks user questions until it can identify an
object that matches with the answer from the user.
Natural Language Processing (NLP) tries to make the
computer capable of understanding commands written in
standard human languages.
Robotics:Industrial assembly robots are used in a
controlled environment. It can perform only programmed
task.
Application of AI
The GPS developed in 1957 by Alan
Newell and Hervert Simon, embodied a
grandiose vision
 The main programming languages used
in AI are Lisp and Prolog
 Prolog especially used in Europe and
Japan, and Lisp in the U.S.

Importance of AI



AI is the field where human brain and
machine talks together. The importance of
AI is very wide. Human brain can be
transformed into a machine format and all
the research is done through AI.
Cognitive Psychology and AI are very
related.
Cognitive Psychology discusses on human
behavior and AI deals how to transform
machine close to human.
Future Perspective





(1) Reducing the time and cost of development is a big
plan for AI.
(2) Allowing students to work collaboratively is
another plan from Researchers.
Perfect rationality: the classical notion of rationality
in decision theory.
Bounded optimality: A bounded optimal agent
behaves as well as possible given its computational
resources.
Game theory studies decision problems in which the
utility of a given action depends not only on chancing
events in the environment but also on the actions of
other agents.
Demos
 Speak with Jesus
 Talk to Julie, With e-cards
 Multilingual Text-to-Speech Systems
 Dr. Werner Wilhelm Webowitz's Office!
 ELIZA - a friend you could never have
before
 Type in text to be synthesized
 Converse with Arty Fishal looney-bin
 Brain the Bot
 Conversation with TIPS
Conclusion


AI just finished with its period of infancy. It
has ramifications that yet remain unknown to
everyone. The effort and research can bring
the surprising innovations.
There are also results which cannot be
foreseen when the computer begins to think
for itself. A computer it can be used in
different ways depending on the user’s
needs.
