This document discusses using classification algorithms to analyze a dataset about interest in vacations. It compares the decision tree and naive Bayes classification models based on accuracy. For the decision tree model, the accuracy was about 45% while sensitivity was around 70%. For the naive Bayes model, the accuracy was higher at about 60% and the sensitivity was 87.5%. Overall, the naive Bayes classification model had better predictive performance than the decision tree model based on this vacation interest dataset.
