Detecting and Mitigating Bias by Treating Fairness as a Symmetry Operation

arXiv:2606.06514v1 Announce Type: cross Abstract: Machine learning systems deployed in high stakes socioeconomic settings routinely display bias. We formalize bias as a symmetry breaking operation: a classifier is fair if its outputs remain invariant under the counterfactual operation of switching a sensitive attribute, with merit features held fixed. We implement loss based regularization as a symmetry restoring mechanism and evaluate the framework on four synthetic datasets with varying levels of noise, correlation, and bias. The framework achieves upwards of 90\% violation reduction, with a

Why this matters
Why now

The proliferation of AI systems in high-stakes domains necessitates robust and auditable fairness mechanisms to prevent societal harm and engender public trust.

Why it’s important

This research provides a formal and practical approach to mitigating bias in AI, which is crucial for ethical deployment, regulatory compliance, and broader societal acceptance of AI technologies.

What changes

The proposed 'symmetry operation' framework offers a novel, quantifiable method for detecting and fixing algorithmic bias, potentially leading to fairer AI systems with widespread implications across industries.
