You learn a decision tree (DT) and a naïve Bayes (NB) model for a data set and use 10-fold cross validation to evaluate them. Suppose that DT has higher accuracy than NB on 7 folds and NB has higher accuracy on 3 folds. a. Based on this result, is one model clearly better than the other? (Yes / No) b. How can you verify with confidence which is better?
