Learning Ensembles of Vision-based Safety Control Filters
Ihab Tabbara, Hussein Sibai
Safety filters in control systems correct nominal controls that violate safety constraints. Designing such filters as functions of visual observations in uncertain and complex envi…
Pre-Trained Vision Models as Perception Backbones for Safety Filters in Autonomous Driving
Yuxuan Yang, Hussein Sibai
End-to-end vision-based autonomous driving has achieved impressive success, but safety remains a major concern. The safe control problem has been addressed in low-dimensional setti…
Recurrence of Nonlinear Control Systems: Entropy and Bit Rates
Hussein Sibai, Enrique Mallada
In this paper, we introduce the notion of recurrence entropy in the context of nonlinear control systems. A set is said to be (-)recurrent if every trajectory that starts in the…
A Grammar for the Representation of Unmanned Aerial Vehicles with 3D Topologies
Piergiuseppe Mallozzi, Hussein Sibai, Inigo Incer +2
We propose a context-sensitive grammar for the systematic exploration of the design space of the topology of 3D robots, particularly unmanned aerial vehicles. It defines production…
