Multi-Agent Resilient Consensus under Intermittent Faulty and Malicious Transmissions (Extended Version)

no code implementations26 Mar 2024 Sarper Aydin, Orhan Eren Akgün, Stephanie Gil, Angelia Nedić

In this work, we consider the consensus problem in which legitimate agents share their values over an undirected communication network in the presence of malicious or faulty agents.

Approximate Multiagent Reinforcement Learning for On-Demand Urban Mobility Problem on a Large Map (extended version)

no code implementations2 Nov 2023 Daniel Garces, Sushmita Bhattacharya, Dimitri Bertsekas, Stephanie Gil

We provide two main theoretical results: 1) characterize the number of taxis $m$ that is sufficient for IA to be stable; 2) derive a necessary condition on $m$ to maintain stability for IA as time goes to infinity.

Surge Routing: Event-informed Multiagent Reinforcement Learning for Autonomous Rideshare

no code implementations5 Jul 2023 Daniel Garces, Stephanie Gil

For our experimental results we consider real NYC ride share data for the year 2022 and information for more than 2000 events across 300 unique venues in Manhattan.

Multiagent Reinforcement Learning for Autonomous Routing and Pickup Problem with Adaptation to Variable Demand

no code implementations28 Nov 2022 Daniel Garces, Sushmita Bhattacharya, Stephanie Gil, Dimitri Bertsekas

We propose a mechanism for switching the originally trained offline approximation when the current demand is outside the original validity region.

Cloud-Cluster Architecture for Detection in Intermittently Connected Sensor Networks

no code implementations3 Oct 2021 Michal Yemini, Stephanie Gil, Andrea J. Goldsmith

The connectivity of each sensor cluster is intermittent and depends on the available communication opportunities of the sensors to the fusion center.

Characterizing Trust and Resilience in Distributed Consensus for Cyberphysical Systems

no code implementations9 Mar 2021 Michal Yemini, Angelia Nedić, Andrea Goldsmith, Stephanie Gil

Further, the expected convergence rate decays exponentially with the quality of the trust observations between agents.

Reinforcement Learning for POMDP: Partitioned Rollout and Policy Iteration with Application to Autonomous Sequential Repair Problems

no code implementations11 Feb 2020 Sushmita Bhattacharya, Sahil Badyal, Thomas Wheeler, Stephanie Gil, Dimitri Bertsekas

In this paper we consider infinite horizon discounted dynamic programming problems with finite state and control spaces, and partial state observations.
