What does the word “worse” indicate in the informal variance comparison?
Question: Answer in one to three sentences, identifying which set's performance is worse and which set provides the comparison reference.
Sample answer: It indicates that the algorithm's dev or test performance is worse than its training performance. The training set provides the reference for measuring the amount of worsening.
Key points:
- Dev or test performance is the worse side of the stated comparison.
- Training performance is the reference side.
Rubric: Credit responses that correctly state the direction from training performance to worse dev or test performance and identify training as the reference.
