What is the origin of a mislabeled example in a dev set?

Question: According to the source text, who introduces the error in a "mislabeled" dev set example and when does this happen relative to the algorithm's execution?

Sample answer: A human labeler introduces the error. This happens before the algorithm encounters the example.

Key points:

  • The error is introduced by a human labeler.
  • It occurs before the machine learning algorithm encounters the example.

Rubric: The answer must state that the human labeler introduced the error and that this occurred before the algorithm processed the data.
