Formal Methods for Autonomous Systems

no code implementations2 Nov 2023 Tichakorn Wongpiromsarn, Mahsa Ghasemi, Murat Cubuktepe, Georgios Bakirtzis, Steven Carr, Mustafa O. Karabag, Cyrus Neary, Parham Gohari, Ufuk Topcu

Formal methods refer to rigorous, mathematical approaches to system development and have played a key role in establishing the correctness of safety-critical systems.

Fine-Tuning Language Models Using Formal Methods Feedback

no code implementations27 Oct 2023 Yunhao Yang, Neel P. Bhatt, Tyler Ingebrand, William Ward, Steven Carr, Zhangyang Wang, Ufuk Topcu

Although pre-trained language models encode generic knowledge beneficial for planning and control, they may fail to generate appropriate control policies for domain-specific tasks.

Safe Reinforcement Learning via Shielding under Partial Observability

no code implementations2 Apr 2022 Steven Carr, Nils Jansen, Sebastian Junges, Ufuk Topcu

Safe exploration is a common problem in reinforcement learning (RL) that aims to prevent agents from making disastrous decisions while exploring their environment.

Byzantine-Resilient Distributed Hypothesis Testing With Time-Varying Network Topology

no code implementations1 Aug 2020 Bo Wu, Steven Carr, Suda Bharadwaj, Zhe Xu, Ufuk Topcu

We study the problem of distributed hypothesis testing over a network of mobile agents with limited communication and sensing ranges to infer the true hypothesis collaboratively.

Verifiable RNN-Based Policies for POMDPs Under Temporal Logic Constraints

no code implementations13 Feb 2020 Steven Carr, Nils Jansen, Ufuk Topcu

Recurrent neural networks (RNNs) have emerged as an effective representation of control policies in sequential decision-making problems.

Counterexample-Guided Strategy Improvement for POMDPs Using Recurrent Neural Networks

no code implementations20 Mar 2019 Steven Carr, Nils Jansen, Ralf Wimmer, Alexandru C. Serban, Bernd Becker, Ufuk Topcu

The particular problem is to determine strategies that provably adhere to (probabilistic) temporal logic constraints.

Human-in-the-Loop Synthesis for Partially Observable Markov Decision Processes

no code implementations27 Feb 2018 Steven Carr, Nils Jansen, Ralf Wimmer, Jie Fu, Ufuk Topcu

The efficient verification of this MC gives quantitative insights into the quality of the inferred human strategy by proving or disproving given system specifications.

Quantifying homologous proteins and proteoforms

no code implementations5 Aug 2017 Dmitry Malioutov, Tianchi Chen, Jacob Jaffe, Edoardo Airoldi, Steven Carr, Bogdan Budnik, Nikolai Slavov

Many proteoforms - arising from alternative splicing, post-translational modifications (PTMs), or paralogous genes - have distinct biological functions, such as histone PTM proteoforms.
