A Primal-Dual-Assisted Penalty Approach to Bilevel Optimization with Coupled Constraints

NeurIPS 2024poster

Interest in bilevel optimization has grown in recent years, partially due to its relevance for challenging machine-learning problems. Several exciting recent works have been centered around developing efficient gradient-based algorithms that can solve bilevel optimization problems with provable guar…

Fair GLASSO: Estimating Fair Graphical Models with Unbiased Statistical Behavior

NeurIPS 2024poster

We propose estimating Gaussian graphical models (GGMs) that are fair with respect to sensitive nodal attributes. Many real-world models exhibit unfair discriminatory behavior due to biases in data. Such discrimination is known to be exacerbated when data is equipped with pairwise relationships encod…
