Analyzing Iterative Benefits and Adaptations of Dev/Test Sets
Question: According to Machine Learning Yearning, why is it recommended to establish an initial dev/test set and evaluation metric, and what should a team do if these targets are no longer aligned with the project's true goals?
Sample answer: Establishing an initial dev/test set and evaluation metric is recommended because it helps the team iterate quickly on their models. However, if the team later finds that the dev/test sets or metric no longer point them in the right direction, they should simply change them and ensure the team is fully informed of the new direction, as making such changes is common and not a major issue.
Key points:
- Initial dev/test sets and metrics enable quick iteration.
- It is common to change dev/test sets or evaluation metrics during a project.
- If they no longer point the team in the right direction, change them and notify the team.
Rubric: To receive full credit, the answer must: 1. Explain that initial sets and metrics are valuable because they facilitate rapid iteration. 2. State that changing them mid-project is common and not problematic if they stop pointing in the correct direction. 3. Emphasize the necessity of communicating the new direction to the team.
