The tanh function is also known as the hyperbolic tangent function. The values go from -1 to +1.
Its mathematical formula is as follows:

The output of the tanh function is zero centered. It is also a non-linear function and so can be used to stack different layers. The tanh function is as shown in the following figure:

Now that we have some idea about what a neural network is, the structure of a neural network, and its different components, let's create a feed-forward neural network using Keras.
