Question

Which among the following is the basic component of artificial neural networks?

(a) Motors

(b) Neurons

(c) Nephrons

(d) Nuclei

The question was posed to me by my college professor while I was bunking the class.

Question is from Techniques in chapter Cognitive Techniques of Cognitive Radio

Answer 1

The correct answer is:

(b) Neurons

In artificial neural networks (ANNs), the basic component is called a neuron (also sometimes referred to as a node or unit). Neurons are the fundamental building blocks of neural networks, modeled after biological neurons in the brain. They receive inputs, process them through an activation function, and produce an output that can be passed to other neurons in the network.

Let's break down the options:

• (a) Motors: Motors are mechanical devices that convert electrical energy into mechanical motion. They are not related to artificial neural networks.

• (b) Neurons: This is the correct answer. Artificial neurons are modeled after biological neurons and are the core computational elements in a neural network. They perform operations like summing inputs and applying activation functions.

• (c) Nephrons: Nephrons are the functional units of the kidneys involved in filtering blood. They are not related to artificial neural networks.

• (d) Nuclei: Nuclei are the central part of a cell that contains genetic material. Again, this is unrelated to artificial neural networks.

Therefore, the basic component of artificial neural networks is neurons, so the correct answer is (b) Neurons.
