Python Machine Learning By Example - Second Edition

Detecting Spam Email with Naive Bayes

As promised, in this chapter, we kick off our supervised learning journey with machine learning classification, specifically, binary classification. We will be learning with the goal of building a high-performing spam email detector. It is a good starting point to learn classification with a real-life example—our email service providers are already doing this for us, and so can we. We will be learning the fundamental concepts of classification, including what it does and its various types and applications, with a focus on solving spam detection using a simple yet powerful algorithm, Naïve Bayes. One last thing: we will be demonstrating how to fine-tune a model, which is an important skill for every data ...
