The structure of an ANN
Here's a visual representation of a neural network:
As you can see from the figure, there are three distinct layers in a neural network: Input layer, Hidden layer (or middle), and Output layer.
There can be more than one hidden layer; however, one hidden layer would be enough to resolve the majority of real-life problems.
Network layers by example
How do we determine the network's topology, and how many neurons to create for each layer? Let's make this determination layer by layer.
The input layer
The input layer defines the number of inputs into the network. For example, let's say you want to create an ANN, which will help you ...
