Scheduling for Urban Air Mobility using Safe Learning

no code implementations28 Sep 2022 Surya Murthy, Natasha A. Neogi, Suda Bharadwaj

This work considers the scheduling problem for Urban Air Mobility (UAM) vehicles travelling between origin-destination pairs with both hard and soft trip deadlines.

Safe Multi-Agent Reinforcement Learning via Shielding

no code implementations27 Jan 2021 Ingy Elsayed-Aly, Suda Bharadwaj, Christopher Amato, Rüdiger Ehlers, Ufuk Topcu, Lu Feng

Multi-agent reinforcement learning (MARL) has been increasingly used in a wide range of safety-critical applications, which require guaranteed safety (e. g., no unsafe states are ever visited) during the learning process. Unfortunately, current MARL methods do not have safety guarantees.

Constrained Active Classification Using Partially Observable Markov Decision Processes

no code implementations10 Aug 2020 Bo Wu, Niklas Lauffer, Mohamadreza Ahmadi, Suda Bharadwaj, Zhe Xu, Ufuk Topcu

The proposed framework relies on assigning a classification belief (a probability distribution) to the attributes of interest.

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.

Near-Optimal Reactive Synthesis Incorporating Runtime Information

no code implementations31 Jul 2020 Suda Bharadwaj, Abraham P. Vinod, Rayna Dimitrova, Ufuk Topcu

We consider the problem of optimal reactive synthesis - compute a strategy that satisfies a mission specification in a dynamic environment, and optimizes a performance metric.

Online Synthesis for Runtime Enforcement of Safety in Multi-Agent Systems

no code implementations23 Oct 2019 Dhananjay Raju, Suda Bharadwaj, Ufuk Topcu

In this approach, which is fundamentally decentralized, the shield on every agent has two components: a pathfinder that corrects the behavior of the agent and an ordering mechanism that dynamically modifies the priority of the agent.

Reward-Based Deception with Cognitive Bias

no code implementations25 Apr 2019 Bo Wu, Murat Cubuktepe, Suda Bharadwaj, Ufuk Topcu

In this paper, we consider deceiving adversaries with bounded rationality and in terms of expected rewards.

Distributed Synthesis of Surveillance Strategies for Mobile Sensors

no code implementations6 Feb 2019 Suda Bharadwaj, Rayna Dimitrova, Ufuk Topcu

We study the problem of synthesizing strategies for a mobile sensor network to conduct surveillance in partnership with static alarm triggers.
