Generalizing Fair Top-$k$ Selection: An Integrative Approach

arXiv:2603.04689v3 Announce Type: replace-cross Abstract: Fair top-$k$ selection, which ensures appropriate proportional representation of members from minority or historically disadvantaged groups among the top-$k$ selected candidates, has drawn significant attention. We study the problem of finding a fair (linear) scoring function with multiple protected groups while also minimizing the disparity from a reference scoring function. This generalizes the prior setup, which was restricted to the single-group setting without disparity minimization. Previous studies imply that the number of protec

Why this matters
Why now

The increasing deployment of AI systems in decision-making necessitates robust frameworks for fairness, especially as these systems are applied to complex, multi-group selection problems.

Why it’s important

This research provides a more sophisticated approach to ensuring equitable outcomes in AI-driven selection processes, addressing a critical ethical and regulatory challenge in AI deployment.

What changes

The ability to integrate multiple protected groups and minimize disparity from reference functions expands the practical applicability and fairness of AI-based top-k selection beyond previous limitations.

Winners
  • · Organizations implementing fair AI systems
  • · Underrepresented groups benefiting from fairer selection
  • · AI ethics researchers and developers
Losers
  • · Systems with implicit biases
  • · Organizations ignoring fairness in AI deployment
Second-order effects
Direct

Improved fairness and reduced bias in AI-driven candidate selection across various domains like hiring, admissions, or resource allocation.

Second

Increased trust and adoption of AI systems in sensitive decision-making contexts as concerns about algorithmic fairness are proactively addressed.

Third

Potential for new regulatory standards and industry best practices to emerge, building on advanced techniques for multi-group fairness and disparity minimization.
