Path Integral Methods with Stochastic Control Barrier Functions

no code implementations23 Jun 2022 Chuyuan Tao, Hyung-Jin Yoon, Hunmin Kim, Naira Hovakimyan, Petros Voulgaris

In this paper, we utilize Stochastic Control Barrier Functions (SCBFs) constraints to limit sample regions in the sample-based algorithm, ensuring safety in a probabilistic sense and improving sample efficiency with a stochastic differential equation.

Learning Image Attacks toward Vision Guided Autonomous Vehicles

no code implementations9 May 2021 Hyung-Jin Yoon, Hamidreza Jafarnejadsani, Petros Voulgaris

While adversarial neural networks have been shown successful for static image attacks, very few approaches have been developed for attacking online image streams while taking into account the underlying physical dynamics of autonomous vehicles, their mission, and environment.
