Handling Adversarial Concept Drift in Streaming Data

no code implementations24 Mar 2018 Tegjyot Singh Sethi, Mehmed Kantardzic

While traditional partially labeled concept drift detection methodologies fail to detect adversarial drifts, the proposed framework is able to detect such drifts and operates with <6% labeled data, on average.

Security Theater: On the Vulnerability of Classifiers to Exploratory Attacks

no code implementations24 Mar 2018 Tegjyot Singh Sethi, Mehmed Kantardzic, Joung Woo Ryu

The adversary assumes a black box model of the defender's classifier and can launch indiscriminate attacks on it, without information of the defender's model type, training data or the domain of application.

A Dynamic-Adversarial Mining Approach to the Security of Machine Learning

no code implementations24 Mar 2018 Tegjyot Singh Sethi, Mehmed Kantardzic, Lingyu Lyua, Jiashun Chen

While most works in the security of machine learning has concentrated on the evasion resistance (a) problem, there is little work in the areas of reacting to attacks (b and c).
