From Cycle Space to Cycle Manifold: Limits and Achievability of Blind False Data Injection Attacks
Xin Li, Chenhan Xiao, Jonathan Cohen +3
A false data injection attack (FDIA) can change the estimated grid state while evading a residual-based bad data detector (BDD). Existing blind attacks learn a low-rank measurement…
Compact and Infinite-Order Error Analysis for Null-Space SVD Estimation
Xin Li, Jonathan Cohen, Rami Puzis
We study null-space estimation from a noisy matrix. For a simple left null space, we first derive an exact compact expression for the error of the smallest left singular vector. We…
Physically Consistent Null Space Alignment for Detection of Low-Magnitude False Data Injection Attacks
Xin Li, Chenhan Xiao, Jonathan Cohen +3
False data injection attacks (FDIAs) introducing small measurement perturbations can still cause large deviations in power system state estimation when the injected signals align w…
Cycle-Space Informed Detection of Autoencoded Blind False Data Injection Attacks on Power Systems
Xin Li, Chenhan Xiao, Jonathan Cohen +3
The rapid growth of AI-driven data centers and large-scale energy storage systems is increasing the reliance of power system operation on real-time measurement data and automated d…
Learning graph topology from metapopulation epidemic encoder-decoder
Xin Li, Jonathan Cohen, Shai Pilosof +1
Metapopulation epidemic models are a valuable tool for studying large-scale outbreaks. With the limited availability of epidemic tracing data, it is challenging to infer the essent…
Projective Psychological Assessment of Large Multimodal Models Using Thematic Apperception Tests
Anton Dzega, Aviad Elyashar, Ortal Slobodin +2
Thematic Apperception Test (TAT) is a psychometrically grounded, multidimensional assessment framework that systematically differentiates between cognitive-representational and aff…
An Evidence-Driven Analysis of Threat Information Sharing Challenges for Industrial Control Systems and Future Directions
Adam Hahn, Rubin Krief, Daniel Rebori-Carretero +3
The increasing cyber threats to critical infrastructure highlight the importance of private companies and government agencies in detecting and sharing information about threat acti…
