There are two types of quantifiers that are used to quantify the statement in an AI system: Universal Quantifier and Existential Quantifier.
3) Which of the mentioned point correctly defines a quantifier in AI?
- Quantifiers are numbers ranging from 0-9.
- Quantifiers are the quantity defining terms which are used with the predicates.
- Quantifiers quantize the term between 0 and 1.
- None of the above
Correct answer: 2
Quantifiers are the quantity defining terms which are used with the predicates.
Quantifiers are the quantity defining terms that are used with the predicates. There are two types of quantifiers that are used to quantify the statement in an AI system: Universal Quantifier and Existential Quantifier.
4) Consider the following statement:
"The universal quantifier is used to define the whole subject population under the predicate."
By reading the above statement, what are the phrases for which the universal quantifier can be applied?
- For all
- For each
- For every
- All of the above
Correct answer: 4
All of the above
The universal quantifier is used to define the whole subject population under the predicate. It can be used anywhere where the phrases like: 'for all', 'for each', 'for every' are used.
5) Consider the following statement:
"The Existential Quantifier is used at the places where only some part of the subject's population is to be defined under the predicate."
By reading the above statement, what are the phrases for which the existential quantifier can be applied?
- For all
- For some
- For every
- All of the above
Correct answer: 2
For some
The Existential Quantifier is used at the places where only some part of the subject's population is to be defined under the predicate. It can be used at all the places where the following phrases are used: 'There exist', 'For some', 'For at least', etc.
