Q31.
What is instance based learning?

a.

It is a family of algorithms that generates new problem instances

b.

It is a family of algorithms that compares new problem instances with instances available in training

c.

It is a family of algorithms that compares new problem instances with each other to determine the degree of similarity

d.

It is a family of algorithms that compares new problem instances with each other to determine the degree of dissimilarity

Discuss
Answer: (b).It is a family of algorithms that compares new problem instances with instances available in training Explanation:Instance based learning is a family of algorithms that compares new problem instances with instances available in training. Instance based learning builds hypotheses directly from training instances. The significance of instance based learning is that hypotheses complexity increases with increase in data.
Q32.
Observe phase involves cognition components.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (b).False Explanation:Observe phase involves user sensory perception and environment sensor components. The orient phase uses cognition components of the aware, adaptive, and cognitive radio architecture.
Q33.
Which among the following stages has to be selected after the orient stage when detailed analysis has to be carried out to determine the course of action?

a.

Observe

b.

Plan

c.

Decide

d.

Act

Discuss
Answer: (b).Plan Explanation:In planning stage, the information collected and organised during the observe phase and the orient phase are used to generate an action plan. By choosing planning stage, the process is carried out in a deliberated and calculated manner.
Q34.
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.
Q35.
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.
Q36.
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.
Q37.
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.
Q38.
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.
Q39.
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.
Q40.
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.
