New Insights into Bootstrapping for Bandits
Sharan Vaswani, Branislav Kveton, Zheng Wen +3
We investigate the use of bootstrapping in the bandit setting. We first show that the commonly used non-parametric bootstrapping (NPB) procedure can be provably inefficient and est…
Offline Evaluation of Ranking Policies with Click Models
Shuai Li, Yasin Abbasi-Yadkori, Branislav Kveton +3
Many web systems rank and present a list of items to users, from recommender systems to search and advertising. An important problem in practice is to evaluate new ranking policies…
Model-Free Linear Quadratic Control via Reduction to Expert Prediction
Yasin Abbasi-Yadkori, Nevena Lazic, Csaba Szepesvari
Model-free approaches for reinforcement learning (RL) and continuous control find policies based only on past states and rewards, without fitting a model of the system dynamics. Th…
Optimizing over a Restricted Policy Class in Markov Decision Processes
Ershad Banijamali, Yasin Abbasi-Yadkori, Mohammad Ghavamzadeh +1
We address the problem of finding an optimal policy in a Markov decision process under a restricted policy class defined by the convex hull of a set of base policies. This problem…
A Continuation Method for Discrete Optimization and its Application to Nearest Neighbor Classification
Ali Shameli, Yasin Abbasi-Yadkori
The continuation method is a popular approach in non-convex optimization and computer vision. The main idea is to start from a simple function that can be minimized efficiently, an…
