Language-Enhanced Latent Representations for Out-of-Distribution Detection in Autonomous Driving

no code implementations2 May 2024 Zhenjiang Mao, Dong-You Jhong, Ao Wang, Ivan Ruchkin

With the rise of large foundation models, multimodal inputs offer the possibility of taking human language as a latent representation, thus enabling language-defined OOD detection.

Zero-shot Safety Prediction for Autonomous Robots with Foundation World Models

no code implementations30 Mar 2024 Zhenjiang Mao, Siqi Dai, Yuang Geng, Ivan Ruchkin

A world model creates a surrogate world to train a controller and predict safety violations by learning the internal dynamic model of systems.

Causal Repair of Learning-enabled Cyber-physical Systems

no code implementations6 Apr 2023 Pengyuan Lu, Ivan Ruchkin, Matthew Cleaveland, Oleg Sokolsky, Insup Lee

However, given the high diversity and complexity of LECs, it is challenging to encode domain knowledge (e. g., the CPS dynamics) in a scalable actual causality model that could generate useful repair suggestions.

Confidence Composition for Monitors of Verification Assumptions

1 code implementation3 Nov 2021 Ivan Ruchkin, Matthew Cleaveland, Radoslav Ivanov, Pengyuan Lu, Taylor Carpenter, Oleg Sokolsky, Insup Lee

To predict safety violations in a verified system, we propose a three-step confidence composition (CoCo) framework for monitoring verification assumptions.
