You should take at least two key documents with you to an interview-your resume and a(n) ______________________________.

Consider a validation set that contains 500 positive examples and 500 negative examples. For R1, suppose the number of positive examples covered by the rule is 200, and the number of negative examples covered by the rule is 50. For R2, suppose the number of positive examples covered by the rule is 100 and the number of negative examples is 5. Compute vIREP for both rules. Which rule does IREP prefer?

The RIPPER algorithm (by Cohen [1]) is an extension of an earlier algorithm

called IREP (by F ?urnkranz and Widmer [3]). Both algorithms apply the

reduced-error pruning method to determine whether a rule needs to be

pruned. The reduced error pruning method uses a validation set to estimate

the generalization error of a classifier. Consider the following pair of rules:

Which statement is true in regard to passing an argument by value to a procedure?

a. A copy of the argument is passed to the procedure. b. A reference to the argument is passed to the procedure. c. The procedure has access to the original argument and can make changes to it. d. A procedure’s parameter list need not agree with the arguments provided to the procedure.
