Temporal Fairness in Decision Making Problems
This work addresses fairness in decision-making for domains requiring historical context, but it is incremental as it builds on existing fairness formulations.
The authors tackled the problem of fairness in decision-making by introducing temporal fairness, which considers the fairness of past decisions over time, and proposed three optimization-based approaches that were qualitatively evaluated in four domains against a non-temporal baseline.
In this work we consider a new interpretation of fairness in decision making problems. Building upon existing fairness formulations, we focus on how to reason over fairness from a temporal perspective, taking into account the fairness of a history of past decisions. After introducing the concept of temporal fairness, we propose three approaches that incorporate temporal fairness in decision making problems formulated as optimization problems. We present a qualitative evaluation of our approach in four different domains and compare the solutions against a baseline approach that does not consider the temporal aspect of fairness.
