Question

Which among the following is not a class of knowledge required for constructing inference hierarchies?

(a) Informal model

(b) Axiomatic model

(c) Ontology model

(d) Behavioural model

I had been asked this question in an interview.

Query is from Architecture in chapter Cognitive Radio Architecture of Cognitive Radio

Answer 1

The correct answer is (d) Behavioural model

Best explanation: A cognitive radio requires significant amount of knowledge to be embedded in inference hierarchies. This includes internal and external knowledge. Internal knowledge is required to reason with itself and external knowledge is required to reason with outside environment. Informal model, axiomatic model, and ontology model are few classes of knowledge that are employed to structure the inference hierarchy.
