Questions and Answers

What is the basic idea behind Ensemble Classifiers?

  • Relying on a complex parameter tuning process
  • Creating a transparent representation of the classifier
  • Using a single classifier for all predictions
  • Building different 'experts' and letting them vote (correct)

What is a disadvantage of Ensemble Classifiers?

  • It provides a compact representation of the classifier
  • It can only include one type of classifier
  • It requires minimal parameter tuning
  • The combined classifier is not so transparent (black box) (correct)

What is the purpose of Unweighted voting in Ensemble of Classifiers?

  • To simplify the implementation process
  • To exclude certain classifiers from the process
  • To combine the classification results from different classifiers (correct)
  • To give more weight to certain classifiers
