Webdard (adversary-unaware) classi er (Section 4), and the op-timal strategy for a classi er playing against this strategy (Section 5). We provide e cient algorithms for computing or approximating these strategies. Experiments in a spam detection domain illustrate the sometimes very large util-ity gains that an adversary-aware classi er can yield, and WebGiven a view W and n independent observations of the system, one is interested in the probability that a Bayesian adversary wrongly predicts the class of W the underlying secret belongs to.
