Which of the following are correct for the neural network? A. The training…

Solution:

The correct ans is option B) A,C,D only

According to general AI concepts, statement B is technically true because neural networks are implemented and simulated using conventional computers such as CPUs and GPUs. However, according to the official UGC NET answer key, the correct option is: A, C and D only

To understand this properly, we must distinguish between:

• Core theoretical characteristics of Neural Networks

• Practical implementation details

Statement-wise Analysis

A. The training time depends upon the size of network.
Correct.

As the number of neurons, layers, and connections increases, the number of parameters also increases. Therefore, more computations are required during forward propagation and backpropagation, increasing the training time.

This is a fundamental performance characteristic of neural networks.

B. Neural network can be simulated on the conventional computer.
Technically true, but partially correct in academic context.

In practice, neural networks are executed on conventional computers using CPUs and GPUs. However, this statement describes the implementation platform, not a core defining property of neural networks.

UGC NET focuses mainly on intrinsic characteristics of neural networks rather than hardware implementation details. Therefore, this statement is often excluded in theoretical classification questions.

C. Neural network mimic the working of the human brain.
Correct.

Artificial Neural Networks are inspired by biological neurons and synaptic connections of the human brain. This biological analogy is one of the foundational concepts of neural networks.

D. A neural network include feedback.
Correct.

Many neural networks, especially Recurrent Neural Networks (RNNs), use feedback connections where outputs are fed back into the system. Even backpropagation itself works as a feedback-based learning mechanism.

Final Conclusion

• A, C, and D represent core conceptual and structural properties of neural networks.

• B represents an implementation fact rather than a defining academic characteristic.

Hence, according to the official UGC NET answer key, the correct option is:

A, C and D only.
