3. Artificial Intelligence
Non Natural /
Simulated
Ability to understand
think and learn
So AI is basically a study of how to make a system which
can think ,behave and act exactly or batter than the human
being act or react.
10. The power and flexibility of simple If-Then-Else logic rules
is enhanced by adding linguistic parameter.
Fuzzy rules are expressed in the form:
IF variable IS set THEN action.
11. FUZZY SET
Let X be a non empty set, A fuzzy set A in X is characterized
by its membership function μ A: X -> [0,1], where μ A(x) is t
he degree of membership of element x in fuzzy set A for each
x ∈ X .
A={1.1,2.1,1.0,2.3}
A={1,2,3,5}
12. OPERATION ON FUZZY
SET
Intersection of Fuzzy Set
The intersection of A and B is defined as
(A ∩ B)(x) = min{A(x), B(x)} = A(x)∩B(x), ∀ x ∈ X,
as demonstrated in figure
13. OPERATION ON FUZZY
SET
Union of Fuzzy Set
The union of A and B is defined as
(A ∪ B)(x) = max{A(x), B(x)} = A(x)∪B(x), ∀ x ∈ X,
as demonstrated in figure……
14. OPERATION ON FUZZY
SET
Complement of Fuzzy Set
The complement of a fuzzy set A is defined as
(~ A)(x) = 1 - A(x)
as demonstrated in figure……
17. Aggregation of similar animals, generally cruising in the
same direction
Termites swarm to build colonies
Birds swarm to find food
Bees swarm to reproduce
18. To forage better
To migrate
As a defense against predators
