The Fairness-Quality Trade-off in Clustering

Neural Information Processing Systems

Fairness in clustering has been considered extensively in the past; however, the trade-off between the two objectives -- e.g., can we sacrifice just a little in the quality of the clustering to significantly increase fairness, or vice-versa?





Last-Iterate Convergence for Generalized Frank-Wolfe in Monotone Variational Inequalities

Neural Information Processing Systems

We study the convergence behavior of a generalized Frank-Wolfe algorithm in constrained (stochastic) monotone variational inequality (MVI) problems. In recent years, there have been numerous efforts to design algorithms for solving constrained MVI problems due to their connections with optimization, machine learning, and equilibrium computation in games.


Multi-Group Proportional Representation in Retrieval

Neural Information Processing Systems

Current approaches to mitigate these representational harms balance the number of retrieved items across population groups defined by a small number of (often binary) attributes. However, most existing methods overlook intersectional groups determined by combinations of group attributes, such as gender, race, and ethnicity.
