Q71.
Which among the following is accomplished by the combination of cognition and effector functions?

a.

Control of user

b.

Control of cognition components

c.

Establish efferent path for control of effectors

d.

Establish efferent path for cognition components

Discuss
Answer: (c).Establish efferent path for control of effectors Explanation:The combination of cognition and effector functions is used to establish the efferent path for the control of effectors. The information services deliver the relevant data to effectors. The cognition function then arranges the data, develops a path, and oversees the flow of information.
Q72.
Which among the following methods may be used to estimate interference in cognitive radio?

a.

Model the radio

b.

Model the user behaviour

c.

Model the channel

d.

Model the propagation of signal

Discuss
Answer: (d).Model the propagation of signal Explanation:he cognition function replicate the propagation of radio signal with good quality to determine the level of interference expected towards other users of the spectrum. It may also be used to verify whether the interference level is within the specified limits imposed by the protocols pertaining to the location.
Q73.
Which among the following is concerned with syntax and semantics of information?

a.

Sequence cluster

b.

Basic sequence

c.

Primitive sequence

d.

Atomic symbols

Discuss
Answer: (a).Sequence cluster Explanation:Sequence clusters are developed on the basis of shared properties. Knowledge discovery and data mining (KDD) and the semantic web provide various means for defining or determining sequence clusters from basic and primitive sequence.
Q74.
What is degree of association required for context cluster?

a.

Space-Time association

b.

Time-Frequency

c.

Frequency-Time association

d.

Space-Time-Frequency association

Discuss
Answer: (d).Space-Time-Frequency association Explanation:Context cluster is developed by space-time-frequency association on a multidimensional level. It is accomplished by using unsupervised machined learning using statistical or non-linear methods.
Q75.
Which among the following is a non-linear machine learning techniques?

a.

Linear regression

b.

Logistic regression

c.

Discriminant analysis

d.

Support vector machines

Discuss
Answer: (d).Support vector machines Explanation:Support vector machine is a supervised machine learning algorithm. It consists of learning algorithms that study data related to classification and regression analysis. It is typically used for creating context clusters in inference hierarchy.
Q76.
The identification of “baseball” from words such as “hit”, “pitch”, and “run” is possible only by the functionality level of context cluster.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (b).False Explanation:Sequence cluster is capable of determining themes from basic sequences that share similar characteristics. The capability of context cluster is to comprehend a discussion on baseball and draw conclusions based on the actions of the user.
Q77.
What is the minimum requirement for taxonomy on radio knowledge?

a.

Speed

b.

Approximate models

c.

Abstraction

d.

Polymorphism

Discuss
Answer: (c).Abstraction Explanation:Abstraction includes the construction of formal and informal models of meta- knowledge ranging from concepts to structured mathematical models of space, time, and frequency. Taxonomy requires a hierarchical model capturing the physical world as well as the internal structure radio.
Q78.
Which among the following may be used for processing speech channels?

a.

Symbol processing

b.

Natural Language processing

c.

Speech synthesiser

d.

Text synthesiser

Discuss
Answer: (b).Natural Language processing Explanation:Speech channels may be processed by using natural language processing facilities that have significant a priori models of language and discourse. Natural language processing is generally embedded in the inference hierarchy of cognitive radio.
Q79.
XTAG caters to the requirement of cognitive radio.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (b).False Explanation:Cognitive radio should initiate transmission when it receives a command “transmit” with an attached message. However XTAG abilities only allow differentiating a verb from a noun but it cannot comprehend the meaning of a command and initiate action.
Q80.
Which among the following is achieved by applying horizontal cognition component s in inference hierarchy?

a.

Radio skills are embedded

b.

Context cluster is developed

c.

Hierarchy is demolished

d.

Hierarchy is established

Discuss
Answer: (a).Radio skills are embedded Explanation:Radio skills are embedded by the introduction horizontal cognition components in inference hierarchy. When radio knowledge is static, radio skills are generated by the intervention of algorithms and inference engines.
