Non-Submodular Maximization via the Greedy Algorithm and the Effects of Limited Information in Multi-Agent Execution
Benjamin Biggs, James McMahon, Philip Baldoni +1
We provide theoretical bounds on the worst case performance of the greedy algorithm in seeking to maximize a normalized, monotone, but not necessarily submodular objective function…
Evaluating the Benefit of Using Multiple Low-Cost Forward-Looking Sonar Beams for Collision Avoidance in Small AUVs
Christopher Morency, Daniel J. Stilwell
We seek to rigorously evaluate the benefit of using a few beams rather than a single beam for a low-cost obstacle avoidance sonar for small AUVs. For a small low-cost AUV, the comp…
Development of a Simulation Environment for Evaluation of a Forward Looking Sonar System for Small AUVs
Christopher Morency, Daniel J. Stilwell, Sebastian Hess
This paper describes a high-fidelity sonar model and a simulation environment that implements the model. The model and simulation environment have been developed to aid in the desi…
Unscented Kalman Filtering on Manifolds for AUV Navigation -- Experimental Results
Stephen T. Krauss, Daniel J. Stilwell
In this work, we present an aided inertial navigation system for an autonomous underwater vehicle (AUV) using an unscented Kalman filter on manifolds (UKF-M). The inertial navigati…
Experiments in Underwater Feature Tracking with Performance Guarantees Using a Small AUV
Benjamin Biggs, Hans He, James McMahon +1
We present the results of experiments performed using a small autonomous underwater vehicle to determine the location of an isobath within a bounded area. The primary contribution…
Fully Decentralized, Scalable Gaussian Processes for Multi-Agent Federated Learning
George P. Kontoudis, Daniel J. Stilwell
In this paper, we propose decentralized and scalable algorithms for Gaussian process (GP) training and prediction in multi-agent systems. To decentralize the implementation of GP t…
