Data Informativeness in Linear Optimization under Uncertainty

Omar Bennouna, Amine Bennouna, Saurabh Amin +1

We study the problem of determining what data is required to solve a decision-making task when only partial information about the state of the world is available. Focusing on linea…

Reducing Contextual Stochastic Bilevel Optimization via Structured Function Approximation

Maxime Bouscary, Jiawei Zhang, Saurabh Amin

Contextual Stochastic Bilevel Optimization (CSBO) extends standard stochastic bilevel optimization (SBO) by incorporating context-dependent lower-level problems. CSBO problems are…

What Data Enables Optimal Decisions? An Exact Characterization for Linear Optimization

Omar Bennouna, Amine Bennouna, Saurabh Amin +1

We study the fundamental question of how informative a dataset is for solving a given decision-making task. In our setting, the dataset provides partial information about unknown p…

Addressing misspecification in contextual optimization

Omar Bennouna, Jiawei Zhang, Saurabh Amin +1

We study a linear contextual optimization problem where a decision maker has access to historical data and contextual features to learn a cost prediction model aimed at minimizing…
