Non-Submodular Maximization via the Greedy Algorithm and the Effects of Limited Information in Multi-Agent Execution

no code implementations18 Oct 2022 Benjamin Biggs, James McMahon, Philip Baldoni, Daniel J. Stilwell

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 under a simple partition matroid constraint.

Fully Decentralized, Scalable Gaussian Processes for Multi-Agent Federated Learning

no code implementations6 Mar 2022 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.

Wasserstein-Splitting Gaussian Process Regression for Heterogeneous Online Bayesian Inference

no code implementations26 Jul 2021 Michael E. Kepler, Alec Koppel, Amrit Singh Bedi, Daniel J. Stilwell

Gaussian processes (GPs) are a well-known nonparametric Bayesian inference technique, but they suffer from scalability problems for large sample sizes, and their performance can degrade for non-stationary or spatially heterogeneous data.

Strictly Decentralized Adaptive Estimation of External Fields using Reproducing Kernels

no code implementations23 Mar 2021 Jia Guo, Michael E. Kepler, Sai Tej Paruchuri, Haoran Wang, Andrew J. Kurdila, Daniel J. Stilwell

Approximations of the evolution of the ideal local estimate $\hat{g}^i_t$ of agent $i$ is constructed solely using observations made by agent $i$ on a fine time scale.
