In most real-world information processing problems, data is not a free resource; its acquisition is rather time-consuming and/or expensive. We investigate how these two factors can be included in supervised classi cation tasks by deriving classi cation as a sequential decision process and making it accessible to Reinforcement Learning. Our method performs a sequential feature selection that learns which features are most informative at each timestep, choosing the next feature depending on the already selected features and the internal belief of the classi er. Experiments on a handwritten digits classi cation task show signi cant reduction in required data for correct classi cation, while a medical diabetes prediction task illustrates variable feature cost minimization as a further property of our algorithm.
