Splitting Guarantees for Prophet Inequalities via Nonlinear Systems
Johannes Brustle, Sebastian Perez-Salazar, Victor Verdugo
The prophet inequality is one of the cornerstone problems in optimal stopping theory and has become a crucial tool for designing sequential algorithms in Bayesian settings. In the…
On First-Order Meta-Reinforcement Learning with Moreau Envelopes
Mohammad Taha Toghani, Sebastian Perez-Salazar, César A. Uribe
Meta-Reinforcement Learning (MRL) is a promising framework for training agents that can quickly adapt to new environments and tasks. In this work, we study the MRL problem under th…
The IID Prophet Inequality with Limited Flexibility
Sebastian Perez-Salazar, Mohit Singh, Alejandro Toriello
In online sales, sellers usually offer each potential buyer a posted price in a take-it-or-leave fashion. Buyers can sometimes see posted prices faced by other buyers, and changing…
Robust Online Selection with Uncertain Offer Acceptance
Sebastian Perez-Salazar, Mohit Singh, Alejandro Toriello
Online advertising has motivated interest in online selection problems. Displaying ads to the right users benefits both the platform (e.g., via pay-per-click) and the advertisers (…
Preserving Diversity when Partitioning: A Geometric Approach
Sebastian Perez-Salazar, Alfredo Torrico, Victor Verdugo
Diversity plays a crucial role in multiple contexts such as team formation, representation of minority groups and generally when allocating resources fairly. Given a community comp…
Differentially Private Online Submodular Maximization
Sebastian Perez-Salazar, Rachel Cummings
In this work we consider the problem of online submodular maximization under a cardinality constraint with differential privacy (DP). A stream of submodular functions over a co…
