Backdoor Attacks and Defenses:- Planted backdoor attacks in deep neural networks (DNN) trained for 2D image classification, 3D point clouds classification, and regression tasks.- Devised post-training and in-flight detection systems against variable backdoor attack settings, benchmark datasets, and DNN architectures.- Proposed an efficient and effective method that achieves post-training backdoor mitigation by correcting the distribution alteration using reverse-engineered triggers.Defense Against Data Poisoning Attacks:- Applied Bayesian information criterion to address the embedded data poisoning (DP) scenario wherein, if DP is present, the poisoned samples are an a priori unknown subset of the training set.
