Regret Bounds and Experimental Design for Estimate-then-Optimize

Samuel Tan, Peter I. Frazier

In practical applications, data is used to make decisions in two steps: estimation and optimization. First, a machine learning model estimates parameters for a structural model rel…

Dynamic Pricing Provides Robust Equilibria in Stochastic Ridesharing Networks

J. Massey Cashore, Peter I. Frazier, Eva Tardos

Ridesharing markets are complex: drivers are strategic, rider demand and driver availability are stochastic, and complex city-scale phenomena like weather induce large scale correl…

Restless Bandits with Many Arms: Beating the Central Limit Theorem

Xiangyu Zhang, Peter I. Frazier

We consider finite-horizon restless bandits with multiple pulls per period, which play an important role in recommender systems, active learning, revenue management, and many other…

An Asymptotically Optimal Index Policy for Finite-Horizon Restless Bandits

Weici Hu, Peter Frazier

We consider restless multi-armed bandit (RMAB) with a finite horizon and multiple pulls per period. Leveraging the Lagrangian relaxation, we approximate the problem with a collecti…

Multi-Step Bayesian Optimization for One-Dimensional Feasibility Determination

J. Massey Cashore, Lemuel Kumarga, Peter I. Frazier

Bayesian optimization methods allocate limited sampling budgets to maximize expensive-to-evaluate functions. One-step-lookahead policies are often used, but computing optimal multi…
