You need to implement a new cost factor scenario for the ad response models as illustrated in the
performance curve exhibit.
Which technique should you use?
A . Set the threshold to 0.5 and retrain if weighted Kappa deviates +/- 5% from 0.45.
B . Set the threshold to 0.05 and retrain if weighted Kappa deviates +/- 5% from 0.5.
C . Set the threshold to 0.2 and retrain if weighted Kappa deviates +/- 5% from 0.6.
D . Set the threshold to 0.75 and retrain if weighted Kappa deviates +/- 5% from 0.15.
Answer: A
Explanation:
Scenario:
Performance curves of current and proposed cost factor scenarios are shown in the following diagram:
The ad propensity model uses a cut threshold is 0.45 and retrains occur if weighted Kappa deviated from 0.1 +/- 5%.
