No-regret optimization of time-varying bilevel problems
Eliabelle Mauduit, Eloïse Berthier, Andrea Simonetto
Bilevel optimization problems arise in many applications where decisions must account for the optimal response of another system, such as in game-theoretic settings. However, these…

Time-varying Gaussian Process Bandit Optimization with Experts: no-regret in logarithmically-many side queries
Eliabelle Mauduit, Eloïse Berthier, Andrea Simonetto
We study a time-varying Bayesian optimization problem with bandit feedback, where the reward function belongs to a Reproducing Kernel Hilbert Space (RKHS). We approach the problem…
