Building a perceptron

Let's start our neural network adventure with a perceptron. A perceptron is a single neuron that performs all the computation. It is a very simple model, but it forms the basis of building up complex neural networks. Here is what it looks like:

The neuron combines the inputs using different weights, and it then adds a bias value to compute the output. It's a simple linear equation relating input values with the output of the perceptron.

How to do it…

1. Create a new Python file, and import the following packages:

   import numpy as np
   import neurolab as nl
   import matplotlib.pyplot as plt

2. Define some input data and their corresponding ...
