Keep Validation and Test Label Fixes Aligned
Apply the same label-correction rule to both the validation set and the test set. If the two sets are cleaned differently, the evaluation conditions no longer match, and a model can be chosen using one labeling standard but judged using another.

Why should the same label-cleaning procedure be used for both the dev set and the test set?
Validation and Test Labels Must Be Handled Consistently
Any label-fixing rule you use for the development set should also be applied to the _____ labels.

What is the main problem if the dev set and test set are labeled using different rules?
It is fine to use one procedure to clean labels for the validation set and a different procedure for the test set if both look accurate overall.
Aligning validation and test label fixes helps prevent the team from optimizing for one score and then being judged by a _____ scoring rule.
