Questions and Answers

What is an advantage of decision trees?

  • They generate understandable rules (correct)
  • They are computationally expensive to train
  • They are not capable of handling regression problems
  • They require a large amount of computation
  • What is a disadvantage of decision trees?

  • They perform classification without requiring much computation
  • They are capable of handling both classification and regression problems
  • They are less appropriate for regression tasks (correct)
  • They are not prone to errors in classification problems
  • What is the purpose of pruning in the context of decision trees?

  • To reduce the accuracy of the model
  • To add more features to the model
  • To increase the complexity of the model
  • To remove unwanted branches of the tree to reduce complexity (correct)
