Questions and Answers

What is the purpose of the RIPPER algorithm?

  • To repeatedly simplify the initial rule set using pruning operators (correct)
  • To incrementally build up a rule set one rule at a time
  • To split the training data into a growing set and a pruning set
  • To form an initial rule set that overfits the growing set

What determines when simplification ends in the RIPPER algorithm?

  • Repeating the simplification process a fixed number of times
  • Using a heuristic method to form the initial rule set
  • Applying any pruning operator that increases the error on the pruning set (correct)
  • Finding a rule that covers all instances in the growing set

In the Boolean case, what is an antecedent of a rule?

  • A set of training data
  • A conjunction of literals (correct)
  • A heuristic method
  • A disjunction of rules
