Short Answer

Benefit of a precise human-level reference for a low-error ML system.

Question: If your machine learning system is already performing well at a 10% error rate, what is the primary benefit of defining your human-level reference as 2% rather than settling for a less precise reference?

Sample answer: Defining a tighter human-level reference of 2% when the system is already at 10% error provides you with better tools to keep improving the system.

Key points:

  • A precise human-level reference is needed when system error is already low.
  • It provides better tools to keep improving the system.

Rubric: The answer must mention that a more precise human-level reference provides better tools or guidance to continue improving an already well-performing system.
