Question: In a concise analytical response, explain the value and the stated limitation of manually reviewing about 20 classifier mistakes on Eyeball dev examples.

Sample answer: Reviewing about 20 classifier mistakes on Eyeball dev examples can start to reveal the major sources of error. Its value is an initial view of which error sources appear important. However, the source describes this view only as a rough sense, so it should not be presented as a complete or exact account.

Key points:

• About 20 classifier mistakes
• Eyeball dev examples
• Manual review
• Rough sense
• Major error sources

Rubric: A strong response identifies the approximate count, the Eyeball dev context, the focus on major error sources, and the limited claim that the resulting understanding is rough.
