TL;DR
This paper introduces a framework for fair classification that balances individual fairness and statistical parity, proposing algorithms to maximize utility while preventing discrimination based on group membership.
Contribution
It presents a novel conceptual framework for fair classification using task-specific similarity metrics and algorithms that enforce fairness constraints, including a method for fair affirmative action.

Approach to achieve statistical parity with similar treatment
Abstract
We study fairness in classification, where individuals are classified, e.g., admitted to a university, and the goal is to prevent discrimination against individuals based on their membership in some group, while maintaining utility for the classifier (the university). The main conceptual contribution of this paper is a framework for fair classification comprising (1) a (hypothetical) task-specific metric for determining the degree to which individuals are similar with respect to the classification task at hand; (2) an algorithm for maximizing utility subject to the fairness constraint, that similar individuals are treated similarly. We also present an adaptation of our approach to achieve the complementary goal of "fair affirmative action," which guarantees statistical parity (i.e., the demographics of the set of individuals receiving any classification are the same as the demographics…
