1 code implementation29 Dec 2020 Vikas Dhiman, Mohammad Javad Khojasteh, Massimo Franceschetti, Nikolay Atanasov

This paper focuses on learning a model of system dynamics online while satisfying safety constraints.

Learning-based attacks in Cyber-Physical Systems: Exploration, Detection, and Control Cost trade-offs

no code implementations21 Nov 2020 Anshuka Rangi, Mohammad Javad Khojasteh, Massimo Franceschetti

We study the trade-offs between the information acquired by the attacker from observations, the detection capabilities of the controller, and the control cost.

Safe Multi-Agent Interaction through Robust Control Barrier Functions with Learned Uncertainties

1 code implementation11 Apr 2020 Richard Cheng, Mohammad Javad Khojasteh, Aaron D. Ames, Joel W. Burdick

Robots operating in real world settings must navigate and maintain safety while interacting with many heterogeneous agents and obstacles.

Probabilistic Safety Constraints for Learned High Relative Degree System Dynamics

1 code implementation L4DC 2020 Mohammad Javad Khojasteh, Vikas Dhiman, Massimo Franceschetti, Nikolay Atanasov

This paper focuses on learning a model of system dynamics online while satisfying safety constraints. Our motivation is to avoid offline system identification or hand-specified dynamics models and allowa system to safely and autonomously estimate and adapt its own model during online operation. Given streaming observations of the system state, we use Bayesian learning to obtain a distributionover the system dynamics.

Learning-based attacks in cyber-physical systems

no code implementations17 Sep 2018 Mohammad Javad Khojasteh, Anatoly Khina, Massimo Franceschetti, Tara Javidi

In the case of scalar plants, we derive an upper bound on the attacker's deception probability for any measurable control policy when the attacker uses an arbitrary learning algorithm to estimate the system dynamics.
