Classifying development-set mistakes with optimization verification
Apply the verification check to each development-set error one by one. If the correct output receives a higher score than the model's chosen output, classify that error as an optimization issue. If the correct output does not score higher, classify the error as a scoring-function issue.

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.
