Data Science and Machine Learning (Theory and Projects) A to Z - Multiple Random Variables: Naive Bayes Classification

The video tutorial introduces the concept of conditional independence and its role in simplifying probability model estimation. It explains the naive Bayes classifier, which assumes conditional independence among features given the class label. The tutorial covers Bayes theorem, density estimation, and how these concepts apply to naive Bayes. It highlights the simplification of estimation using individual conditional densities and discusses the common use of normal distributions in modeling. The video concludes with a transition to regression topics.

In what scenarios might the conditional independence assumption not hold true, and how does that affect the classifier's performance?
