Scale-free adaptive planning for deterministic dynamics & discounted rewards
Peter L. Bartlett, Victor Gabillon, Jennifer Healey +1
We address the problem of planning in an environment with deterministic dynamics and stochastic rewards with discounted returns. The optimal value function is not known, nor are th…
Derivative-Free & Order-Robust Optimisation
Victor Gabillon, Rasul Tutunov, Michal Valko +1
In this paper, we formalise order-robust optimisation as an instance of online learning minimising simple regret, and propose Vroom, a zero'th order optimisation algorithm capable…
A simple parameter-free and adaptive approach to optimization under a minimal local smoothness assumption
Peter L. Bartlett, Victor Gabillon, Michal Valko
We study the problem of optimizing a function under a \emph{budgeted number of evaluations}. We only assume that the function is \emph{locally} smooth around one of its global opti…
