Claim 13:
14. A system, comprising:
a processor; and
memory that stores computer program logic for execution by the processor, the computer program logic comprising instructions for:
receiving a query for classification from an adversary having an adversary type that corresponds to an adversarial strength that is used to perturb the data in the query, the adversary type not being directly known by the learner,
determining a strength of the adversary based on a predicted adversary type distribution, wherein the determining the strength of the adversary comprises:
completing one or more trials of a Bayesian game, and
based upon determining that a predetermined number of trials has not been completed, initiating one or more rounds of a self play game;

selecting a classifier from the classifier ensemble, the classifier having been trained with at least one of clean data or adversarial data, and the classifier having a classification strength that is commensurate with the determined strength of the adversary, and
classifying the query using the selected classifier.
