Questions

$1.$ Build decision tress from the Data using algorithms discussed in the class. Report model performance based on accuracy, error, sensitivity $($recall$),$ specificity, and precision using k$-$fold cross validation.

$2.$ Compare the models using ROC curves and Precision$-$Recall graphs

$3.$ Compute precision and recall using micro and macro averaging approaches. Interpret the results.
