Cyberphysical Security Through Resiliency: A Systems-centric Approach
Cody Fleming, Carl Elks, Georgios Bakirtzis +4
Cyber-physical systems (CPS) are often defended in the same manner as information technology (IT) systems -- by using perimeter security. Multiple factors make such defenses insuff…
Value-Decomposition Multi-Agent Actor-Critics
Jianyu Su, Stephen Adams, Peter A. Beling
The exploitation of extra state information has been an active research area in multi-agent reinforcement learning (MARL). QMIX represents the joint action-value using a non-negati…
An Ontological Metamodel for Cyber-Physical System Safety, Security, and Resilience Coengineering
Georgios Bakirtzis, Tim Sherburne, Stephen Adams +3
System complexity has become ubiquitous in the design, assessment, and implementation of practical and useful cyber-physical systems. This increased complexity is impacting the man…
Counterfactual Multi-Agent Reinforcement Learning with Graph Convolution Communication
Jianyu Su, Stephen Adams, Peter A. Beling
We consider a fully cooperative multi-agent system where agents cooperate to maximize a system's utility in a partial-observable environment. We propose that multi-agent systems mu…
