Sequential Counterfactual Risk Minimization

1 code implementation23 Feb 2023 Houssam Zenati, Eustache Diemert, Matthieu Martin, Julien Mairal, Pierre Gaillard

Counterfactual Risk Minimization (CRM) is a framework for dealing with the logged bandit feedback problem, where the goal is to improve a logging policy using offline data.

Efficient Kernel UCB for Contextual Bandits

1 code implementation11 Feb 2022 Houssam Zenati, Alberto Bietti, Eustache Diemert, Julien Mairal, Matthieu Martin, Pierre Gaillard

While standard methods require a O(CT^3) complexity where T is the horizon and the constant C is related to optimizing the UCB rule, we propose an efficient contextual algorithm for large-scale problems.

Treatment Targeting by AUUC Maximization with Generalization Guarantees

no code implementations17 Dec 2020 Artem Betlei, Eustache Diemert, Massih-Reza Amini

In real life scenarios, when we do not have access to ground-truth individual treatment effect, the capacity of models to do so is generally measured by the Area Under the Uplift Curve (AUUC), a metric that differs from the learning objectives of most of the Individual Treatment Effect (ITE) models.

Individual Treatment Prescription Effect Estimation in a Low Compliance Setting

no code implementations7 Aug 2020 Thibaud Rahier, Amélie Héliou, Matthieu Martin, Christophe Renaudin, Eustache Diemert

Individual Treatment Effect (ITE) estimation is an extensively researched problem, with applications in various domains.
