This formulation allows distinct fairness concepts to be specified in a common framework. We further propose a novel reranking algorithm that optimizes for a desired trade-off between utility and fairness of a recommendation list.

In this paper, we study the bundle design problem for offering personalized bundles of services using historical consumer redemption data.
