Question 830

A university services design uses Label-quality review in order to reduce unfair predictions caused by inconsistent judgments in labeled examples. Which technical description is accurate?

  1. Label auditing checks whether target outcomes are accurate and consistently assigned.
  2. A balanced test set gives meaningful coverage to groups at risk of being overlooked.
  3. Historical labels can encode past discrimination that a model learns as predictive signals.
  4. Proxy variables can cause decisions to correlate with sensitive traits even when those traits are excluded.

Explanation

Correct Answer

A:

For the proposed university services use, the key operating principle is that label auditing checks whether target outcomes are accurate and consistently assigned; that mechanism is what enables Label-quality review to reduce unfair predictions caused by inconsistent judgments in labeled examples. The technical limitation—more training rows will not fix systematic annotation mistakes—needs a separate check.

Question 833

In a subscription services discussion of Training-set representation for the goal to prevent a hiring screen from learning mainly from one applicant population, which TWO statements reflect its actual operation? (Choose TWO.)

  1. Training-set representation operates according to this purported mechanism: historical labels can encode past discrimination that a model learns as predictive signals.
  2. Broad average accuracy can conceal poor outcomes for small or underrepresented groups.
  3. The main purpose of Training-set representation is to compare the effect of changing a classification threshold on different groups instead of to prevent a hiring screen from learning mainly from one applicant population.
  4. The described method removes the need to consider the stated limitation because inclusive design incorporates users with varied linguistic and accessibility needs.
  5. Representative training coverage includes the people and situations in the intended deployment population.

Explanation

Correct Answers

B:

This is a valid caution for Training-set representation: broad average accuracy can conceal poor outcomes for small or underrepresented groups. In a subscription services setting, the concern follows even when representative training coverage includes the people and situations in the intended deployment population; it must be checked against the particular requirement to prevent a hiring screen from learning mainly from one applicant population.

E:

This accurately identifies the operation behind Training-set representation: representative training coverage includes the people and situations in the intended deployment population. It offers the mechanism needed to prevent a hiring screen from learning mainly from one applicant population in the subscription services example, with the boundary that broad average accuracy can conceal poor outcomes for small or underrepresented groups.

Incorrect Answers

A:

The stated behavior is for Historical bias recognition, not for Training-set representation in a subscription services requirement to prevent a hiring screen from learning mainly from one applicant population. Historical labels can encode past discrimination that a model learns as predictive signals is a real capability of the alternative, whereas the concept under review works because representative training coverage includes the people and situations in the intended deployment population.

C:

The stated behavior is for Fairness tradeoff review, not for Training-set representation in a subscription services requirement to prevent a hiring screen from learning mainly from one applicant population. Fairness review examines several group outcomes and business constraints together is a real capability of the alternative, whereas the concept under review works because representative training coverage includes the people and situations in the intended deployment population.

D:

This assertion incorrectly waives the limitation of Training-set representation in the subscription services context. The relevant boundary is that broad average accuracy can conceal poor outcomes for small or underrepresented groups; selecting a technology to prevent a hiring screen from learning mainly from one applicant population does not remove that underlying requirement.
