Thinking that understanding the basic theory about Naive Bayes would help understanding lesson 5, and I happened to present a paper about sentiment classification on the Business Communication class, I humbly want to share part of my presentation on using Naive Bayes Classifier to classify sentiment of movie reviews. I am too lazy to transform all the formulas into markdown so I just take the screen-shot of my word document. The complete version of my presentation which includes maximum entropy and support vector machine classifier is also attached. Hope it helps.
