Fuzzy sets
Fuzzy Sets

Is this sentence true or false?


Probabiltiy vs. Fuzziness

Probability describes the uncertainty of an event occurrence.

Fuzziness describes event ambiguity.

Whether an event occurs is RANDOM.

To what degree it occurs is FUZZY.


Probability:

There is a 50% chance of an apple

being in the refrigerator.

Fuzzy:There is a half an apple in therefrigerator.


Fuzzy logic acknowledges and exploits the tolerance for uncertainty and imprecision.
