Hands-On Artificial Intelligence for Cybersecurity

Simple NN example – perceptron

In this section, we will show a simple NN model, known as a perceptron.

NNs and DL are subfields of ML aimed at emulating the human brain's learning capabilities. NN and DL will be addressed in more depth in Chapter 3, Ham or Spam? Detecting Email Cybersecurity Threats with AI, and Chapter 8, GANs – Attacks and Defenses.

However rudimentary it is, a perceptron is nonetheless able to adequately classify samples that tend to group together (in technical terms, those that are linearly separable).

One of the most common uses of a perceptron in the field of cybersecurity, as we will see, is in the area of spam filtering.

In the following example, we will use the scikit-learn implementation of the perceptron algorithm: ...
