  • 06-3Have you checked and prevented potential biases in data labeling?
    • A supervised learning model requires labeling of training data. However, there may be biases in labeling due to the reflection of labeler’s specific intentions, mistaken omission of feature information, and unconscious judgment.

    • Such biases may result from the labeler’s lack of expertise or absence of consistent standards for work and decisions. Hence, labelers should identify potential causes of bias in advance and prevent bias by evaluating the labeling result and training on work standards. It is also best to recruit diverse labelers to minimize bias in each labeler, or have a sufficient number of reviewers to prevent bias.
