LaMDA: Language Models for Dialog Applications
Romal Thoppilan, Daniel De Freitas, Jamie Hall +57
We present LaMDA: Language Models for Dialog Applications. LaMDA is a family of Transformer-based neural language models specialized for dialog, which have up to 137B parameters an…
Adversarial Regression for Detecting Attacks in Cyber-Physical Systems
Amin Ghafouri, Yevgeniy Vorobeychik, Xenofon Koutsoukos
Attacks in cyber-physical systems (CPS) which manipulate sensor readings can cause enormous physical damage if undetected. Detection of attacks on sensors is crucial to mitigate th…
Optimal Detection of Faulty Traffic Sensors Used in Route Planning
Amin Ghafouri, Aron Laszka, Abhishek Dubey +1
In a smart city, real-time traffic sensors may be deployed for various applications, such as route planning. Unfortunately, sensors are prone to failures, which result in erroneous…
Resilient Supervisory Control of Autonomous Intersections in the Presence of Sensor Attacks
Amin Ghafouri, Xenofon D. Koutsoukos
Cyber-physical systems (CPS), such as autonomous vehicles crossing an intersection, are vulnerable to cyber-attacks and their safety-critical nature makes them a target for malicio…
Optimal Thresholds for Anomaly-Based Intrusion Detection in Dynamical Environments
Amin Ghafouri, Waseem Abbas, Aron Laszka +2
In cyber-physical systems, malicious and resourceful attackers could penetrate the system through cyber means and cause significant physical damage. Consequently, detection of such…
Vulnerability of Fixed-Time Control of Signalized Intersections to Cyber-Tampering
Amin Ghafouri, Waseem Abbas, Yevgeniy Vorobeychik +1
Recent experimental studies have shown that traffic management systems are vulnerable to cyber-attacks on sensor data. This paper studies the vulnerability of fixed-time control of…
