Before you start

Quiz for Lab 08: Naive Bayes Classifier. The last tasks compare Naive Bayes with KNN. Answer every task, then press Check answers at the bottom: each answer is marked, the explanations appear, and you get a score per skill.

Assumptions unless stated otherwise

  • A higher class score means the class is preferred.
  • Naive Bayes is used for classification.
  • When comparing classes, the common evidence denominator can be ignored.
  • Features are assumed conditionally independent given the class.

How answers are scored

  • Numbers: type the value as a decimal (0.4) or a fraction (2/5); a percentage also works for probabilities.
  • Rows: one choice per row; each correct row earns its share of the points.
  • Select all that apply: scores only when the selection is exactly right.
  • Your answers are saved in this browser only, so you can leave and come back. Nothing is sent anywhere.
