AB - Many machine learning systems rely on data collected in thewild from untrusted sources, exposing the learning algorithms to datapoisoning. Attackers can inject malicious data in the training datasetto subvert the learning process, compromising the performance of thealgorithm producing errors in a targeted or an indiscriminate way. Labelflipping attacks are a special case of data poisoning, where the attackercan control the labels assigned to a fraction of the training points. Evenif the capabilities of the attacker are constrained, these attacks havebeen shown to be effective to significantly degrade the performance ofthe system. In this paper we propose an efficient algorithm to performoptimal label flipping poisoning attacks and a mechanism to detect andrelabel suspicious data points, mitigating the effect of such poisoningattacks.
