New framework tackles algorithmic recourse in competitive scenarios

Researchers have developed a new framework called "recourse under competition" to address the challenge of algorithmic recourse when individuals compete for limited resources. This framework aims to ensure that recourse recommendations remain valid even when widespread implementation could alter the acceptance threshold. By jointly optimizing for recommendation recipients and the necessary score targets, the system balances recourse cost with post-shift validity for initially rejected individuals. Experiments indicate that personalized score targets can improve validity at a higher cost, while common score targets offer a better cost-validity trade-off for lower validity levels. AI

IMPACT This research could improve fairness and accuracy in machine learning systems where outcomes are competitive.
