Q51.
What among the following is not characteristic of a causal model?

a.

Causal models make predictions about the behaviour of the system

b.

Causal models assign truth value

c.

Causal models do not include the effect of intervention

d.

Causal models determine probabilistic dependence of variables

Discuss
Answer: (c).Causal models do not include the effect of intervention Explanation:Causal models are mathematical models that describe the causal relationship present within a system or a group. The causal relationships are extracted using statistical data. In research-quality and industrial-level cognitive radio, planning tools include causal models.
Q52.
Which among the following techniques are used for reasoning?

a.

Plan calculus

b.

Plan sequence

c.

Plan series

d.

Plan theory

Discuss
Answer: (a).Plan calculus Explanation:Plan calculus applies reasoning over time, user identity, space, and context. It offers information such as when and where. It also provides the context, and reports internal requests. The context may involve location, action, state of existence, etc.
Q53.
Which among the following function is used in the plan phase?

a.

User sensory perception

b.

Cognition function

c.

Local effectors

d.

System application

Discuss
Answer: (c).Local effectors Explanation:The set of actions selected by the plan phase are performed by local effector functions. Each action is mapped as a request by plan calculus. Plan calculus generates and compares plans and finds conflicts.
Q54.
Which among the following is the building block of causal tool?

a.

Graph theory

b.

Probability

c.

Logic

d.

Variables

Discuss
Answer: (d).Variables Explanation:Variables are the building blocks of causal models. The values may represent the likelihood of occurrence of an event, a characteristic of an individual, the population of a system, or any quantitative value. Language, logic, probability, and graphs are tools used for developing causal models.
Q55.
What is the function of decide phase?

a.

Generation of alternatives

b.

Evaluation of alternatives

c.

Establishment of priority

d.

Selection among alternatives

Discuss
Answer: (d).Selection among alternatives Explanation:The decide phase selects from a number of options generated by the planning phase. It is responsible for allocating computational and radio resources to support software in accordance to the activated plan.
Q56.
Which among the following holds true for autonomous decision?

a.

Correlation between present condition and reference condition is high

b.

Correlation between present condition and reference condition is low

c.

Covariance between present condition and reference condition is positive

d.

Covariance between present condition and reference condition is negative

Discuss
Answer: (a).Correlation between present condition and reference condition is high Explanation:Autonomous decisions are taken when the correlation between present and reference condition is high. It is preferred when the radio has been operated previously in the same spatial-temporal context. Knowledge representation depends on the radio procedure components.
Q57.
What kind of decision relies on external confirmation?

a.

Tactical decision

b.

Independent decision

c.

Predictable decision

d.

Tentative decision

Discuss
Answer: (d).Tentative decision Explanation:Tentative decisions are consulted with the user for confirmation before execution. This leads to better user experience in the future. In certain situations, the selected option is executed and the user interaction is recorded to resolve conflict.
Q58.
The decision phase controls the timing of alerts in a radio.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (a).True Explanation:Other than selecting a particular option from a set of plans, the decision phase chooses the timing to alert a user. It might alert immediately or put off the interruption according to the circumstances of the user (such as until after a meeting).
Q59.
What function belongs to external oriented actions in act phase?

a.

Parse images and videos

b.

Compose messages for interaction with environment

c.

Parse incoming RF signals

d.

Parse texts

Discuss
Answer: (b).Compose messages for interaction with environment Explanation:The function of the act phase is to engage in contact with outside world by composing messages for interaction with the local environment. The message may also have to be transferred to another cognitive radio or to a cognitive node.
Q60.
Which among the following may be used to represent information that is continuously changing?

a.

Knowledge Manipulation Language

b.

Web Ontology Language

c.

RoXen Macro Language

d.

Radio eXtensibleMarkup Language

Discuss
Answer: (b).Web Ontology Language Explanation:Web Ontology Language is a family of knowledge representation languages for developing ontologies. Ontologies are similar in structure to class hierarchies in object-oriented programming. Ontologies are suitable for information that changes continuously such as the data found on the Internet.
