On Frequentist Regret of Linear Thompson Sampling

Nima Hamidi, Mohsen Bayati

This paper studies the stochastic linear bandit problem, where a decision-maker chooses actions from possibly time-dependent sets of vectors in Rd and receives noisy re…

The Unreasonable Effectiveness of Greedy Algorithms in Multi-Armed Bandit with Many Arms

Mohsen Bayati, Nima Hamidi, Ramesh Johari +1

We investigate a Bayesian k-armed bandit problem in the \emph{many-armed} regime, where k≥T​ and T represents the time horizon. Initially, and aligned with recent…

A General Theory of the Stochastic Linear Bandit and Its Applications

Nima Hamidi, Mohsen Bayati

Recent growing adoption of experimentation in practice has led to a surge of attention to multiarmed bandits as a technique to reduce the opportunity cost of online experiments. In…
