3. What Is A.I. ?
A.I. is a branch of computer science that studies the computational requirements
for tasks such as perception, reasoning and learning and develop systems to
perform those tasks
The field of Artificial intelligence strives to understand and build intelligent
entities
A.I.
Strong A.I.
M/C can think and
act like human
Weak A.I.
Some thinking like features
can be added to M/C
4. DEFINITIONS
* Artificial intelligence (AI) is an area of
computer science that emphasizes the
creation of intelligent machines that work and
react like humans
* AI works with pattern matching methods which attempt to
describe objects , events or processes in terms of their
qualitative features and logical and computational
Relationship.
5. History Of AI
The branch of computer science concerned with making
computers behave like humans.
This term was coined in 1956 by John McCarthy at the
Massachusetts Institute of Technology
Currently, no computers exhibit full artificial
intelligence .In May, 1997,an IBM super-computer called
Deep Blue defeated world chess champion
Gary Kasparov in a chess match.

6. Major Branches Of AI
Perceptive system
A system that approximates the way a human sees, hears, and
feels objects
Vision system
Capture, store, and manipulate visual images and pictures
Robotics
Mechanical and computer devices that perform tedious tasks
with high precision
Expert system
Stores knowledge and makes inferences

7. Major Branches of AI (2)
Learning system
Computer changes how it functions or reacts to situations based
on feedback
Natural language processing
Computers understand and react to statements and commands
made in a “natural” language, such as English
Neural network
Computer system that can act like or simulate the functioning of
the human brain

10. Fxpert System
Expert systems :
Expert system is an artificial intelligence
program that has expert-level knowledge about a
particular domain and knows how to use its
knowledge to respond properly

11. Limitations of Expert Systems
Not widely used or tested
Limited to relatively narrow problems
Cannot readily deal with “mixed” knowledge
Possibility of error
Cannot refine own knowledge base
Difficult to maintain
May have high development costs
Raise legal and ethical concerns

12. Capabilities of Expert Systems
Artificial Intelligence(AI) 12
Gfg Strategic goal setting
Decision making
Planning
Design
Quality control and monitoring
Explore impact of strategic goals
Impact of plans on resources
Integrate general design principles and
manufacturing limitations
Provide advise on decisions
Monitor quality and assist in finding solutions
Look for causes and suggest solutionsDiagnosis
13. When to Use an Expert System
Provide a high potential payoff or significantly reduced
downside risk
Capture and preserve irreplaceable human expertise
Provide expertise needed at a number of locations at
the same time or in a hostile environment that is
dangerous to human health
Provide expertise that is expensive or rare
Develop a solution faster than human experts can

14. Components of an
Expert System (1)
Knowledge base
Stores all relevant information, data, rules, cases, and
relationships used by the expert system
Inference engine
Seeks information and relationships from the
knowledge base and provides answers, predictions, and
suggestions in the way a human expert would
Rule
A conditional statement that links given conditions to
actions or outcomes
15. Components of an
Expert System (2)
Fuzzy logic
A specialty research area in computer science that allows
shades of gray and does not require everything to be
simply yes/no, or true/false
Backward chaining
A method of reasoning that starts with conclusions and
works backward to the supporting facts
Forward chaining
A method of reasoning that starts with the facts and
works forward to the conclusions
