(15 points) Consider the mutual information based feature selection. Suppose we have the follow- ing table (the entries in table indicate counts) for the spam versus and non-spam emails: "prize" = 1 "prize" = 0 "spam" = 1 150 10 "spam" = 0 1000 15000 "hello" = 1 "hello" = 0 "spam" = 1 155 5 "spam" = 0 14000 2000 Given the two tables above, calculate the mutual information for the two keywords, "prize" and "hello" respectively. Which keyword is more informative for deciding whether or not the email is a spam
