Lecture 5 Bayes Classifier and Naive Bayes

Lecture 5 Bayes Classifier and Naive Bayes

The Naive Bayes assumption implies that the words in an email are conditionally independent given that you know that an email is spam or not. Clearly this is not true. Neither the words of spam or not-spam emails are drawn independently at random. However the resulting classifiers can work well in prctice even if this assumption is violated.
