Q51.
What is the purpose of knowledge based system?

a.

To explicitly describe knowledge

b.

To accumulate large database

c.

To recycle data

d.

To develop languages

Discuss
Answer: (a).To explicitly describe knowledge Explanation:Knowledge based system is a computer program that provides solution to complex problems by using knowledge and reasoning. It is important that the knowledge is described explicitly. This assists easy application of reasoning to new knowledge.
Q52.
Which statement is used to encapsulate the introduction of a new model into the existing models?

a.

<iCRplatform/>

b.

<Self/>

c.

<Self>

d.

<iCRplatform>

Discuss
Answer: (b).<Self/> Explanation:The act phase introduces new models to internal structures and updates existing model. The addition of new specify-explore-refine model is encapsulated by the statement <Self/>. Knowledge acquisition in act phase generates data structures.
Q53.
Which among the following factors affect knowledge representation?

a.

Radio resources

b.

Plan phase information

c.

Actuators

d.

Orient phase information

Discuss
Answer: (a).Radio resources Explanation:The act stage activates operations with pre-fixed amount of resources and time. The knowledge representation depends on the radio resources, and radio knowledge being applied to the parameters contributing to the process.
Q54.
Why is the RXML statement <Self/> added in cognitive radio?

a.

To add cognitive architecture to cognitive radio

b.

To define functions

c.

To define interfaces

d.

To eliminate components

Discuss
Answer: (a).To add cognitive architecture to cognitive radio Explanation:The cognitive radio must evaluate, monitor, and access all resources including affirming downloads. The statement <Self/> is a self-referential component. It is used to add the aware, adaptive, and cognitive radio architecture to aware, adaptive and cognitive radio.
Q55.
What capability demand was boosted upon introduction of machine learning in cognitive radio?

a.

RF sensing

b.

Haptic sensing

c.

Knowledge acquisition

d.

Resource acquisition

Discuss
Answer: (c).Knowledge acquisition Explanation:Availability of knowledge of a certain degree is essential in cognitive radio to extract user knowledge pertaining to information services. The repeated occurrences of similar activity are considered as learning opportunities. This is exploited by machine learning for incremental knowledge acquisition.
Q56.
Which among the following methods enable identification of learning opportunities in machine learning in cognitive radio?

a.

Gamma distribution

b.

Joint probability statistics

c.

Variance

d.

Uniform distribution

Discuss
Answer: (b).Joint probability statistics Explanation:Machine learning uses joint probability statistics for exploiting learning opportunities that arise due to repeated occurrence of similar situation. High quality use cases help to locate classes of user and knowledge that fine tune the set of services being provided.
Q57.
Which among the following is not a guided principle relating to self-monitoring behaviour of cognitive radio?

a.

Unrestricted while loops cannot be used

b.

Only bounded iterations are permitted

c.

Unrestricted first order predicate calculus is permitted

d.

Unrestricted for loops cannot be used

Discuss
Answer: (c).Unrestricted first order predicate calculus is permitted Explanation:Self-monitoring behaviour is required in a cognitive radio to ensure bounded usage of resources within bounded time. First order predicate calculus is avoided as it is not possible to determine the period of completion. Bounded iterations whose completion time is independent of the calculation of iteration control of the loop.
Q58.
Learning is a function of perception.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (a).True Explanation:Learning is a function of perception, observation, decision, and action. Learning also occurs by the introduction of new specific-explore-refine models to existing structure. Learning involves the comparison of prior and current states.
Q59.
Which among the following is an outcome of inference hierarchy?

a.

Organisation of data structures

b.

Control of internal flow of information

c.

Control of external flow of information

d.

Dissemination of knowledge

Discuss
Answer: (a).Organisation of data structures Explanation:The inference hierarchy organises the information from observation to action phase in the corresponding data structures. It aids in including machine learning with real-time performance during the wake epoch.
Q60.
Which among the following occupies the bottom most position in inference hierarchy?

a.

Primitive stimuli

b.

Atomic symbols

c.

Primitive symbols

d.

Atomic stimuli

Discuss
Answer: (d).Atomic stimuli Explanation:Atomic stimuli refer to the external signals available from the outside world in unprocessed form. It includes the RF, image, location, and acoustic information that enter from the outside environment.
