Fairness Invariants: A Relational Approach to Explaining and Mitigating Fairness Bugs

The paper introduces REMI, a framework that treats counterfactual fairness as a relational invariant discovery problem. By learning over paired examples, REMI identifies input regions where fairness is violated and generates interpretable rule-based models—fairness invariants—that can block or relabel unfair predictions without retraining the underlying model. Experiments on symbolic and neural network programs show REMI localizes fairness bugs in over 83% of cases and reduces discriminatory decisions in black-box models by up to 70%.

Tuning Derivatives for Causal Fairness in Machine Learning

arXiv:2605. 05882v2 Announce Type: replace-cross Abstract: Artificial-intelligence systems are becoming ubiquitous in society, yet their predictions typically inherit biases with respect to protected attributes such as race, gender, or age.

Let's Unlearn Stereotypes Before Decision-Making: Assessing the Impact of Intrinsic Bias Mitigation on Downstream Fairness in LLMs

arXiv:2509. 16462v2 Announce Type: replace-cross Abstract: Large Language Models (LLMs) are increasingly used in high-stakes decision-making systems, where biased predictions can reinforce social and economic disparities.

Mitigating Demographic Disparities in Explanation-Human Alignment via Rationale Regularization

The paper investigates explanation fairness in hate‑speech detection, noting that high classification accuracy does not guarantee equally plausible explanations for all demographic groups. Using the HateXplain dataset, the authors introduce Plausibility‑EFG, a metric that quantifies the largest difference in explanation plausibility across groups by comparing model‑generated token attributions with human‑annotated rationales. Experiments with BERT, RoBERTa, and an adversarially trained ADV‑RoBERTa show that the latter improves both classification performance and alignment with human rationales while reducing explanation disparities, and the study highlights that predictive fairness and explanation fairness are related but distinct objectives.
