Causality-Based Parametric Control Barrier Function for Safe Multi-Vehicle Interaction
Yiwei Lyu, Caleb Chang, John M. Dolan
Safe control has been widely studied in various safety-critical applications, for instance, autonomous driving. In order to ensure the autonomous vehicle does not collide with othe…
Do as the Romans Do: Learning Universal Behaviors from Heterogeneous Agents
Caleb Chang, Davin Win Kyi, Natasha Jaques +1
Humans often acquire new skills by observing others, since observed behaviors implicitly reveal how to act in an environment. However, observations drawn from a heterogeneous popul…
Learning Probabilistic Responsibility Allocations for Multi-Agent Interactions
Isaac Remy, Caleb Chang, Karen Leung
Human behavior in interactive settings is shaped not only by individual objectives but also by shared constraints with others, such as safety. Understanding how people allocate res…
Characterizing Cyber Attacks against Space Infrastructures with Missing Data: Framework and Case Study
Ekzhin Ear, Jose Luis Castanon Remy, Caleb Chang +3
Cybersecurity of space infrastructures is an emerging topic, despite space-related cybersecurity incidents occurring as early as 1977 (i.e., hijacking of a satellite transmission s…
Space Cybersecurity Testbed: Fidelity Framework, Example Implementation, and Characterization
Jose Luis Castanon Remy, Caleb Chang, Ekzhin Ear +1
Cyber threats against space infrastructures, including satellites and systems on the ground, have not been adequately understood. Testbeds are important to deepen our understanding…
