When Is a Dev-Set Error Attributed to Optimization?
In the optimization-versus-verification check, what condition indicates that a dev-set mistake should be blamed on the optimization algorithm rather than on the model’s ability to represent the target function?

When Is a Dev-Set Error Attributed to Optimization?
True or False: If the best achievable development-set score is already no better than the current system's score, the optimization algorithm is the main problem.
A development-set example is counted as a mistake by the _____ metric when it lowers the score used to tune the model.
Which condition indicates that a wrong development-set example is an optimization problem rather than a scoring problem?
If the development set is easier than the test set because the examples come from different sources, improving development accuracy may fail to improve test performance.
When the evaluation score prefers the wrong output, the dev-set issue is a _____ error.

Order the steps for deciding whether each development-set mistake points to the optimizer or the scoring rule.
What does Score_A(S*) ≤ Score_A(S_out) indicate in dev set analysis?
A troubleshooting method can start by analyzing one example and then be extended to every error in the development set.
