Q81.
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.
Q82.
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.
Q83.
What is the function of horizontal cognition components with radio skills?

a.

Monitor user behaviour

b.

Send request to user

c.

Control radio personalities

d.

Train internal behaviour

Discuss
Answer: (c).Control radio personalities Explanation:The horizontal cognition components control radio personalities. It is carried out during the observe phase and the orient phase of the wake cycle. The radio skills are included in active data structures during the process of training or sleeping.
Q84.
Which among the following is avoided in horizontal specify-explore-refine models?

a.

Resource dependencies

b.

Control dependencies

c.

Data dependencies

d.

Logical dependencies

Discuss
Answer: (d).Logical dependencies Explanation:The specify-explore-refine models are continually compared to their associated phase in the hierarchical structure. This enables the model to respond on time and to take immediate action. This is primarily due to the lack of logical dependencies among components.
Q85.
What is the function of a sensory pre-processing system?

a.

Conversion of atomic stimuli into primitive sequence

b.

Conversion of atomic stimuli into atomic symbols

c.

Conversion of atomics symbols into atomic stimuli

d.

Conversion of primitive sequence into atomic stimuli

Discuss
Answer: (b).Conversion of atomic stimuli into atomic symbols Explanation:The conversion of atomic stimuli into atomic symbols by using a sensory pre-processing subsystem. Advanced signal and video processing tools are required to isolate atomic symbols in industrial cognitive radio.
Q86.
When does the extraction of primitive sequence from higher aggregates is carried out?

a.

Wake cycle

b.

Prayer cycle

c.

Sleep cycle

d.

Live cycle

Discuss
Answer: (c).Sleep cycle Explanation:The formation of atomic symbols can take place by two procedures. The atomic stimuli may combine to form atomic symbol. The atomic symbols may also be formed by learning from higher aggregates. The first type occurs during wake cycle while the second is carried out during sleep cycle.
Q87.
Which phase is responsible for fast retrieval of data?

a.

Act

b.

Plan

c.

Decide

d.

Observe

Discuss
Answer: (d).Observe Explanation:Observe phase accumulates all sensor data. The data is parsed and allotted to various processing nodes for fast parallel retrieval. Observe phase occupies large amount of storage to support memory based learning techniques.
Q88.
Which among the following specifies the correct sequence of steps followed to obtain primitive sequence in speech?

a.

Isolate the basic sequence, analyse the basic sequence, analyse the primitive sequence

b.

Isolate the basic sequence, isolate the primitive sequence, analyse the basic sequence

c.

Analyse the basic sequence, isolate the basic sequence, analyse the primitive sequence

d.

Isolate the basic sequence, analyse the primitive sequence, analyse the basic sequence

Discuss
Answer: (a).Isolate the basic sequence, analyse the basic sequence, analyse the primitive sequence Explanation:In speech, the sensor obtains input that correlate with the definition of basic sequence. In order to obtain the primitive sequence, the basic sequence is isolated from background noise. The basic sequence is analysed to identify potential boundaries of primitive sequence. The primitive sequence is then extracted and statistically analysed.
Q89.
Which among the following is used to save radio skill set knowledge?

a.

RaXon Macro Language

b.

Web Ontology Language

c.

Knowledge Query and Manipulation Language

d.

Radio Knowledge Representation Language

Discuss
Answer: (d).Radio Knowledge Representation Language Explanation:The radio skills obtained by horizontal cognition components associated with each phase are saved in radio knowledge representation language (RKRL) frame. The skill sets are also developed by information from a priori knowledge which is available in the form of RKRL frames.
Q90.
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

Discuss
Answer: (d).Behavioural model 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.
