ATLAS-AL: Adaptive Trust-Region for Latent Adversarial Searches via Active Learning
Marsalis Gibson, Claire Tomlin, Shankar Sastry
Security evaluation of learning-based systems requires more than just testing the system against a fixed collection of attacks. It requires adaptive mechanisms that can efficiently…
Traffic Control via Connected and Automated Vehicles: An Open-Road Field Experiment with 100 CAVs
Jonathan W. Lee, Han Wang, Kathy Jang +61
The CIRCLES project aims to reduce instabilities in traffic flow, which are naturally occurring phenomena due to human driving behavior. These "phantom jams" or "stop-and-go waves,…
Hacking Predictors Means Hacking Cars: Using Sensitivity Analysis to Identify Trajectory Prediction Vulnerabilities for Autonomous Driving Security
Marsalis Gibson, David Babazadeh, Claire Tomlin +1
Adversarial attacks on learning-based multi-modal trajectory predictors have already been demonstrated. However, there are still open questions about the effects of perturbations o…
Parallel Network Flow Allocation in Repeated Routing Games via LQR Optimal Control
Marsalis Gibson, Yiling You, Alexandre Bayen
In this article, we study the repeated routing game problem on a parallel network with affine latency functions on each edge. We cast the game setup in a LQR control theoretic fram…
Reachability Analysis for FollowerStopper: Safety Analysis and Experimental Results
Fang-Chieh Chou, Marsalis Gibson, Rahul Bhadani +2
Motivated by earlier work and the developer of a new algorithm, the FollowerStopper, this article uses reachability analysis to verify the safety of the FollowerStopper algorithm,…
Multi-Adversarial Safety Analysis for Autonomous Vehicles
Gilbert Bahati, Marsalis Gibson, Alexandre Bayen
This work in progress considers reachability-based safety analysis in the domain of autonomous driving in multi-agent systems. We formulate the safety problem for a car following s…
Integrated Framework of Vehicle Dynamics, Instabilities, Energy Models, and Sparse Flow Smoothing Controllers
Jonathan W. Lee, George Gunter, Rabie Ramadan +25
This work presents an integrated framework of: vehicle dynamics models, with a particular attention to instabilities and traffic waves; vehicle energy models, with particular atten…
Scalable Learning of Safety Guarantees for Autonomous Systems using Hamilton-Jacobi Reachability
Sylvia Herbert, Jason J. Choi, Suvansh Sanjeev +3
Autonomous systems like aircraft and assistive robots often operate in scenarios where guaranteeing safety is critical. Methods like Hamilton-Jacobi reachability can provide guaran…
