-The researchers [] proposed the Reject On Negative Impact (RONI) defense which ignores all the training data points that have a substantial negative impact on the classification accuracy.
-RONI defense system consists of two classifiers. One classifier is trained using the base training set and the other is trained with the base set and potentially malicious data. If the errors of those two classifiers differ significantly from each other the data is labeled as malicious.
-RONI defense defends against exploratory and causative attacks. For defending against exploratory attacks, in which an attacker can create an evaluation distribution that the learner predicts poorly, the defender can limit the access to the training procedure and data, making it harder for an attacker to apply reverse engineering. For defending against the causative attacks, in which an attacker can manipulate both training and evaluation distributions, the defender can employ previously described defense using two classifiers.

-Machine learning is a powerful and adaptive tool that enabled tackling problems that so far required humans. It also enabled the automation of threat recognition tasks.
+Machine learning is a powerful and adaptive tool that enabled tackling problems that so far required humans. It also enabled the automation of threat recognition tasks. In this paper, multiple applications of machine learning in cybersecurity were shown. Most of the problems were solved using supervised learning and classification since their required classifying input into safe or malicious categories. For classification tasks, researchers tested multiple classifiers, each with its own pros and cons, and they chose what they considered the best ones for the task at hand.
