In this section, we'll create a simple network with one hidden layer, which solves the XOR function. As we mentioned at the end of the previous chapter, the XOR function is a linearly inseparable problem, hence the need for a hidden layer. The source code will allow you to easily modify the number of layers and the number of neurons per layer, so you can try a number of different scenarios. We'll not use any ML libraries. Instead, we'll implement them from scratch only with the help of numpy. We'll also use matplotlib to visualize the results:
- With that, let's start by importing these libraries:
import matplotlib.pyplot as pltimport numpy from matplotlib.colors import ListedColormap ...
