Abstract: The disclosed embodiments disclose techniques for performing universal post-training backdoor detection and mitigation for classifiers. Mitigation of overfitting for a trained classifier begins with receiving the trained classifier and a clean dataset that spans a plurality of classes for the trained classifier. A set of input patterns are used to calculate classification margins for the trained classifier, and maximum classification margins are calculated for one or more classes of the trained classifier. Overfitting can then be mitigated by reducing one or more of these calculated maximum classification margins while maintaining the accuracy of the trained classifier for the clean dataset. In some embodiments, a backdoor detector may also detect target classes for a putative backdoor in the trained classifier upon detecting that the corresponding maximum classification margins for those target classes are anomalously high compared to the maximum classification margins of other classes.
