In one to three sentences, explain how a validation set can guide which model ideas deserve more work.
Question: In one to three sentences, explain how checking performance on a validation set helps a team decide which model ideas to keep improving and which to stop pursuing.
Sample answer: When a model change is evaluated on the validation set, the team gets fast evidence about whether the change helps in a meaningful way. That feedback makes it easier to keep developing promising ideas and drop ones that do not improve results.
Key points:
- Validation-set evaluation gives quick evidence of improvement or no improvement
- This information helps the team choose ideas to continue refining and ideas to discard
Rubric: Full credit: mentions that validation-set measurement quickly shows whether an idea improves performance and that this guides the decision to keep or drop the idea. Partial credit: mentions only one of these ideas. No credit: unrelated answer or missing the main point.

How does dev set performance help a team choose which ideas to keep improving?
What do teams usually try once dev and test sets are fixed?
What do teams typically do after they have set up dev and test sets?
