Suppose you want to use Naive Bayes to perform document classification (binary clas- sification) using the bag of words model where we have D documents and a total of n words. How many probabilities would a Naive Bayes classifier need to learn? Suppose, your boss says, change the order of sentences in each document and re-learn the Naive Bayes classifier, do you expect the learned model to be different? Briefly explain
