Q51.
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.
Q52.
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.
Q53.
What is the atomic symbol equivalent of an image?

a.

Small group of blocks

b.

Small group of phoneme

c.

Small group of pixels

d.

Small group of points

Discuss
Answer: (c).Small group of pixels Explanation:Atomic symbols succeedatomic stimuli. It is the most fundamental symbolic units of a domain. Phonemes are considered as the most primitive form of speech. Pixels are considered most primitive form of an image.
Q54.
Which among the following is obtained by collection of atomic symbols?

a.

Aggregated sequence

b.

Atomic sequence

c.

Primitive sequence

d.

Primary sequence

Discuss
Answer: (c).Primitive sequence Explanation:Primitive sequence is formed by assembling similar atomic symbols in a coherent manner. Primitive sequences generally have spatial or temporal likeliness which is visible and can be identified from a heap of information.
Q55.
Which among the following categories include an accelerometer?

a.

Global effectors

b.

Environmental sensors

c.

Local effectors

d.

User interface sensors

Discuss
Answer: (b).Environmental sensors Explanation:Environmental sensors measure various characteristics in the surrounding domain. This includes temperature, vibration, power, exposure to light, position of sun, velocity, etc. It enables perception.
Q56.
Adaption may be pre-programmed.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (a).True Explanation:Awareness enables adaption. Adaption is ability to direct a change according to input obtained from sensing. Adaption may be achieved without introducing learning through pre-programming. However, it is not possible to program all possible changes hence the next level of capability cognition is required.
Q57.
What method may introduce a trade-off between time and space in cognitive radio structure?

a.

Introduction of fully programmed solutions

b.

Introduction of partial solutions

c.

Introduction of real time solutions

d.

Introduction of large memory

Discuss
Answer: (b).Introduction of partial solutions Explanation:The introduction of partial solutions help in solving complex problems because a subset of problems relating to the complex problem will be solved first. The number of calculations may not be completely reduced but there is slight development in the overall computational burden.
Q58.
What is the full form of NP complexity?

a.

Non-deterministic polynomial time

b.

Non-linear polynomial time

c.

Non-probabilistic polynomial time

d.

Non-trainable polynomial time

Discuss
Answer: (a).Non-deterministic polynomial time Explanation:The non-deterministic polynomial time is a complexity class in the computational complexity theory. It is used to differentiate decision problems. NP is a collection of decision problems. When a decision results in action, it must have proof that can be confirmed in polynomial time by a deterministic Turing machine.
Q59.
Which among the following is a characteristic that need not be compulsorily present to overcome self-referential inconsistency in cognitive radio?

a.

Definition of process as a priori tightly bounded time epochs

b.

Step counting function

c.

Susceptible to Gödel-Turing condition

d.

Pre-defined actions that uses O (1) resources

Discuss
Answer: (c).Susceptible to Gödel-Turing condition Explanation:In order to computationally support real time transmission and reception, a process must be defined in priori tightly bounded time epochs. A pre-defined action that uses O (1) resources is defined in advance and a reliable step counting function must be present. This will help in avoiding unpredictable usage of resources and unpredictable self-referential loops.
Q60.
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.
