3 cards from this section. Quick, good the night before a test.
What do we mean by 'prior weights' in the Bayesian Decision Matrix?
Think about the initial importance assigned before receiving feedback.
What is Bayes’ theorem used for?
Consider how new information changes our understanding.
What is the primary purpose of the Bayesian Decision Matrix?
Consider how prior knowledge and new information interact in this matrix.
True or False: Prior weights are assigned randomly.
Think about where these weights come from.
You're working on a new software application. You initially assign weights based on the importance of user features: Usability - 0.4, Performance - 0.3, Essential Functions - 0.3. After a user testing session, you discover Usability scored 6 out of 10, Performance 8 out of 10, and Essential Functions 5 out of 10. How would you update the weights using Bayes’ theorem?
Break down the problem into calculating initial scores followed by redistributing the weights.
Discuss a scenario where the Bayesian Decision Matrix could lead to a misinterpretation of user needs. Illustrate how the presence of bias might distort the weights.
Consider scenarios where a biased sample might lead to skewed results.
