IBCL: Zero-shot Model Generation for Task Trade-offs in Continual Learning

1 code implementation4 Oct 2023 Pengyuan Lu, Michele Caprio, Eric Eaton, Insup Lee

Upon a new task, IBCL (1) updates a knowledge base in the form of a convex hull of model parameter distributions and (2) obtains particular models to address task trade-off preferences with zero-shot.

Fulfilling Formal Specifications ASAP by Model-free Reinforcement Learning

no code implementations25 Apr 2023 Mengyu Liu, Pengyuan Lu, Xin Chen, Fanxin Kong, Oleg Sokolsky, Insup Lee

We propose a model-free reinforcement learning solution, namely the ASAP-Phi framework, to encourage an agent to fulfill a formal specification ASAP.

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.

Mako: Semi-supervised continual learning with minimal labeled data via data programming

no code implementations29 Sep 2021 Pengyuan Lu, Seungwon Lee, Amanda Watson, David Kent, Insup Lee, Eric Eaton, James Weimer

This tool achieves similar performance, in terms of per-task accuracy and resistance to catastrophic forgetting, as compared to fully labeled data.
