Development and validation of an interpretable machine learning-based calculator for predicting 5-year weight trajectories after bariatric surgery: a multinational retrospective cohort SOPHIA study

Patrick Saux, Pierre Bauvin, Violeta Raverdy +31

Background Weight loss trajectories after bariatric surgery vary widely between individuals, and predicting weight loss before the operation remains challenging. We aimed to develo…

Risk-aware linear bandits with convex loss

Patrick Saux, Odalric-Ambrym Maillard

In decision-making problems such as the multi-armed bandit, an agent learns sequentially by optimizing a certain feedback. While the mean reward criterion has been extensively stud…

Bregman Deviations of Generic Exponential Families

Sayak Ray Chowdhury, Patrick Saux, Odalric-Ambrym Maillard +1

We revisit the method of mixture technique, also known as the Laplace method, to study the concentration phenomenon in generic exponential families. Combining the properties of Bre…

From Optimality to Robustness: Dirichlet Sampling Strategies in Stochastic Bandits

Dorian Baudry, Patrick Saux, Odalric-Ambrym Maillard

The stochastic multi-arm bandit problem has been extensively studied under standard assumptions on the arm's distribution (e.g bounded with known support, exponential family, etc).…
