Machine Learning for Data Mining

A sample neural network model

Let's use an example to understand neural networks in more detail:

Notice that every neuron in the Input Layer is connected to every neuron in the Hidden Layer, for example, Input 1 is connected to the first, second, and even the third neuron in the Hidden Layer. This implies that there will be three different weights, and these weights will be a part of three different equations.

This is what happens in this example:

• The Hidden Layer intervenes between the Input Layer and the Output Layer.
• The Hidden Layer allows for more complex models with nonlinear relationships.
• There are many equations, so the influence ...
