GUTS: Generalized Uncertainty-Aware Thompson Sampling for Multi-Agent Active Search

no code implementations4 Apr 2023 Nikhil Angad Bakshi, Tejus Gupta, Ramina Ghods, Jeff Schneider

We conduct field tests using our multi-robot system in an unstructured environment with a search area of approximately 75, 000 sq.

Disaster Response Thompson Sampling

Cost Aware Asynchronous Multi-Agent Active Search

no code implementations5 Oct 2022 Arundhati Banerjee, Ramina Ghods, Jeff Schneider

Multi-agent active search requires autonomous agents to choose sensing actions that efficiently locate targets.

Decision Making Thompson Sampling

Multi-Agent Active Search using Detection and Location Uncertainty

no code implementations9 Mar 2022 Arundhati Banerjee, Ramina Ghods, Jeff Schneider

We then build a decision making algorithm on this inference method that uses Thompson sampling to enable decentralized multi-agent active search.

Optimal Data Detection and Signal Estimation in Systems with Input Noise

no code implementations5 Aug 2020 Ramina Ghods, Charles Jeon, Arian Maleki, Christoph Studer

Practical systems often suffer from hardware impairments that already appear during signal generation.

Compressive Sensing

Asynchronous Multi Agent Active Search

no code implementations25 Jun 2020 Ramina Ghods, Arundhati Banerjee, Jeff Schneider

Active search refers to the problem of efficiently locating targets in an unknown environment by actively making data-collection decisions, and has many applications including detecting gas leaks, radiation sources or human survivors of disasters using aerial and/or ground robots (agents).
