The Challenger: When Do New Data Sources Justify Switching Machine Learning Models?

Vassilis Digalakis, Christophe Pérignon, Sébastien Saurin +1

The paper proposes a framework for deciding when to replace an existing predictive model with a new one that uses additional data features, linking learning‑curve dynamics to the e…

Flexibility allocation in random bipartite matching markets: exact matching rates and dominance regimes

Taha Ameen, Flore Sentenac, Sophie H. Yu

This paper studies how a fixed flexibility budget should be allocated across the two sides of a balanced bipartite matching market. We model compatibilities via a sparse bipartite…

On the Average-Case Performance of Greedy for Maximum Coverage

Eric Balkanski, Jason Chatzitheodorou, Flore Sentenac

For the classical maximum coverage problem, the greedy algorithm achieves a worst-case approximation, which is optimal unless . The notion of coverage…

A uniformity principle for spatial matching

Taha Ameen, Flore Sentenac, Sophie H. Yu

Platforms matching spatially distributed supply to demand face a fundamental design choice: given a fixed total budget of service range, how should it be allocated across supply no…

Balancing optimism and pessimism in offline-to-online learning

Flore Sentenac, Ilbin Lee, Csaba Szepesvari

We consider what we call the offline-to-online learning setting, focusing on stochastic finite-armed bandit problems. In offline-to-online learning, a learner starts with offline d…

Online Matching in Geometric Random Graphs

Flore Sentenac, Nathan Noiry, Matthieu Lerasle +2

We investigate online maximum cardinality matching, a central problem in ad allocation. In this problem, users are revealed sequentially, and each new user can be paired with any p…
