Short Answer

What should a team do if its evaluation data no longer reflects real-world use?

Question: If a team finds that the real distribution their system will face is different from the dev/test sets, what is the appropriate response?

Sample answer: They should revise the dev/test sets so they better match the real-world distribution the system needs to handle.

Key points:

  • Recognize that the evaluation data no longer matches deployment conditions.
  • Rebuild or adjust the dev/test sets to reflect the target distribution more closely.

Rubric: The response must say that the dev/test sets need to be updated or changed so they are more representative of the actual distribution.
