Physical Backdoor Trigger Activation of Autonomous Vehicle using Reachability Analysis

no code implementations24 Mar 2023 Wenqing Li, Yue Wang, Muhammad Shafique, Saif Eddin Jabari

Recent studies reveal that Autonomous Vehicles (AVs) can be manipulated by hidden backdoors, causing them to perform harmful actions when activated by physical triggers.

PiDAn: A Coherence Optimization Approach for Backdoor Attack Detection and Mitigation in Deep Neural Networks

no code implementations17 Mar 2022 Yue Wang, Wenqing Li, Esha Sarkar, Muhammad Shafique, Michail Maniatakos, Saif Eddin Jabari

Based on our theoretical analysis and experimental results, we demonstrate the effectiveness of PiDAn in defending against backdoor attacks that use different settings of poisoned samples on GTSRB and ILSVRC2012 datasets.

Distributed dynamic modeling and monitoring for large-scale industrial processes under closed-loop control

no code implementations7 Sep 2018 Wenqing Li, Chunhui Zhao, Biao Huang

Based on the distributed monitoring system, a two-level monitoring strategy is proposed to check different influences on process characteristics resulting from changes of the operating conditions and control action, and thus the two changes can be well distinguished from each other.
