2) "The Certainty Factor (CF) is a numeric value which tells us about how likely an event or a statement is supposed to be true."
What is the range of this numeric value, i.e. Certainty Factor?
- Between 0 to 1 (Both inclusive)
- Between 0 to 1 (Both exclusive)
- Between -1 to +1
- None of the above
Correct answer: 3
Between -1 to +1
The value of the Certainty factor lies between -1.0 to +1.0, where the negative 1.0 value suggests that the statement can never be true in any situation, and the positive 1.0 value defines that the statement can never be false.
3) Consider the following statement:
"The value of the Certainty factor lies between -1.0 to +1.0, where the negative 1.0 value suggests that the statement can never be true in any situation, and the positive 1.0 value defines that the statement can never be false."
What does the value 0 denote for CF?
- Half true Half False
- Somewhat true but not entirely false
- Agent has no information about the event
- Both a. and b.
Correct answer: 3
Agent has no information about the event
The value 0 suggests that the agent has no information about the event or the situation.
4) What is the minimum Certainty factor which decided whether the value is true or false?
- 0
- -1
- +1
- Is decided in prior to every problem
Correct answer: 4
Is decided in prior to every problem
A minimum Certainty factor is decided for every case through which the agent decides whether the statement is true or false.
