Naive Bayes

Part of the Data Science Roadmap.

Summary

A fast, simple classifier based on Bayes' theorem, assuming features are independent (an assumption that's often technically wrong but works surprisingly well in practice) — especially strong for text classification.

How to Learn This

  • 1Fit a Naive Bayes classifier on a simple text classification dataset.
  • 2Learn why the 'naive' independence assumption rarely holds, yet the model still performs well.
  • 3Compare its speed to a more complex model on the same dataset.
