Feasible Arm Identification

Abstract: We introduce the feasible arm identification problem, a pure exploration multi-armed bandit problem where the agent is given a set of D-dimensional arms and a polyhedron P={x:Axb}RD. Pulling an arm gives a random vector and the goal is to determine, using a fixed budget of T pulls, which of the arms have means belonging to P. We propose three algorithms MD-UCBE, MD-SAR, and MD-APT and provide a unified analysis establishing upper bounds for each of them. We also establish a lower bound that matches up to constants the upper bounds of MD-UCBE and MD-APT. Finally, we demonstrate the effectiveness of our algorithms on synthetic and real-world datasets.
