2. Introduction to Artificial Intelligence
 Making a computer, a computer-controlled robot, or a software think
intelligently, in the similar manner the intelligent humans think.
 Borrowing characteristics from human intelligence, and applying them as
algorithms in a computer friendly way.
 Variety of perspectives:-
1. Business perspective
2. Programming perspective

3. History of Artificial Intelligence
 1956 - John McCarthy coined the term "artificial intelligence“.
 1952-1962 – The IBM introduced game playing program
 1958 –John McCarthy invented LISP.
 1973 - The Assembly Robotics group at Edinburgh University builds Freddy, the
Famous Scottish Robot, capable of using vision to locate and assemble models.
 1980’s - Lisp Machines developed and marketed.
 2000’s - Interactive robot pets become commercially available, realizing the vision
of the 18th cen. novelty toy makers.

4. Types of Artificial Intelligence
 Linguistic intelligence
 Intra-personal intelligence
 Musical intelligence
 Logical mathematical intelligence
 Spatial intelligence

5. Sub-fields of Artificial Intelligence
 Neural Networks – e.g. brain modelling, time series prediction, classification
 Vision – e.g. object recognition, image understanding
 Robotics – e.g. intelligent control, autonomous exploration
 Expert Systems – e.g. decision support systems, teaching systems
 Speech Processing– e.g. speech recognition and production
 Natural Language Processing – e.g. machine translation
 Planning – e.g. scheduling, game playing

6. Expert systems
 The expert systems are the computer applications developed to solve complex
problems in a
 particular domain, at the level of extra-ordinary human intelligence and
expertise.

7. Characteristics of Expert systems
 High performance
 Understandable
 Reliable
 High responsive

8. Terminology
 Autonomous Agent – A hardware (or software) based system that has the
following properties:
autonomy - able to operate without the direct intervention of humans
or others
social ability - able to interact with other agents and possibly humans
reactivity - able to perceive their environment and respond to
changes that occur in it
 Agency – Software that gathers information about an environment and
takes actions

9. Artificial Intelligence and Robotics
 Robotics:
Robots are the artificial agents acting in real world environment. Robotics is a
branch of AI, which is composed of Electrical Engineering, Mechanical Engineering,
and Computer Science for designing, construction, and application of robots.

10. Difference between Artificial
Intelligence and Robotics
AI Programs Robots
They usually operate in computer
stimulated worlds.
They operate in real physical world
The input to an AI program is in
symbols and rules.
Inputs to robots is analog signal in
the form of speech waveform or
images
They need general purpose
computers to operate on.
They need special hardware with
sensors and effectors.

11. Languages used in Artificial
Intelligence
 1st language: Lisp and its variants were historically used in AI research,
but it doesn't seem like anyone uses it anymore.
 Latest languages: As always, the answer depends on the research
group and subfield. C++,Java,MATLAB and Python are all used extensively.
A large portion of machine learning and modeling seems to be done in
Matlab (for research and proof of concept) and C++ (for speed, if the
Matlab code ever works well enough), though plenty is done in Python
and a few important libraries have been built in Java

12. Applications
 Gaming
 Natural Language Processing
It is possible to interact with the computer that understands natural language spoken
By humans.
 Vision Systems
For example,
 Police use computer software that can recognize the face of criminal with the stored
portrait made by forensic artist.
 Disaster rescue

13. Conclusion
 That always interest and surprise us with the new ideas, topics, innovations,
products …etc.
 AI is still not implemented as the films representing it,
 At the end, we’ve been in this research through the AI definitions, history, and
applications of AI in public, applications of AI and robotics.
 Future, maybe it will be a whole society of robots.
