Summary
- What is new: A randomized method for post-processing rankings without needing the protected attribute.
- Why this is important: Lack of fairness in machine learning for ranking-related problems, with the complication of not always having the protected attribute and having multiple measures of fairness.
- What the research proposes: A new post-processing method that randomizes rankings to improve fairness without requiring protected attribute information.
- Results: The method showed robustness with respect to P-Fairness and improved effectiveness in terms of Normalized Discounted Cumulative Gain (NDCG) compared to existing methods.
