Neural networks are said to be inspired from the human brain. Just as our brains are made up of several neurons connected to each other, neural networks are made up of programmatically designed neurons that are connected to each other. We call the programmatically designed neurons—perceptrons.
Perceptrons form the atomic unit of neural networks. They take as input a set of numbers (one or many), multiply the input with some weights, and return an output.
The following diagram illustrates this concept:
In Figure 2, it takes input as three values and returns an output. What happens inside ...
