Fully Decentralized Design of Initialization-free Distributed Network Size Estimation

no code implementations15 Jan 2024 Donggil Lee, Taekyoo Kim, Seungjoon Lee, Hyungbo Shim

In this paper, we propose a distributed scheme for estimating the network size, which refers to the total number of agents in a network.

Data-driven Discovery of Chemotactic Migration of Bacteria via Machine Learning

no code implementations25 Aug 2022 Yorgos M. Psarellis, Seungjoon Lee, Tapomoy Bhattacharjee, Sujit S. Datta, Juan M. Bello-Rivas, Ioannis G. Kevrekidis

The resulting data-driven PDE can then be simulated to reproduce/predict computational or experimental bacterial density profile data, and estimate the underlying (unmeasured) chemonutrient field evolution.

Learning black- and gray-box chemotactic PDEs/closures from agent based Monte Carlo simulation data

no code implementations26 May 2022 Seungjoon Lee, Yorgos M. Psarellis, Constantinos I. Siettos, Ioannis G. Kevrekidis

We exploit Automatic Relevance Determination (ARD) within a Gaussian Process framework for the identification of a parsimonious set of collective observables that parametrize the law of the effective PDEs.

Multi-armed Bandit Algorithm against Strategic Replication

no code implementations23 Oct 2021 Suho Shin, Seungjoon Lee, Jungseul Ok

We consider a multi-armed bandit problem in which a set of arms is registered by each agent, and the agent receives reward when its arm is selected.

Coarse-scale PDEs from fine-scale observations via machine learning

no code implementations12 Sep 2019 Seungjoon Lee, Mahdi Kooshkbaghi, Konstantinos Spiliotis, Constantinos I. Siettos, Ioannis G. Kevrekidis

In this paper, we introduce a data-driven framework for the identification of unavailable coarse-scale PDEs from microscopic observations via machine learning algorithms.

Linking Gaussian Process regression with data-driven manifold embeddings for nonlinear data fusion

no code implementations16 Dec 2018 Seungjoon Lee, Felix Dietrich, George E. Karniadakis, Ioannis G. Kevrekidis

In this paper, we will explore mathematical algorithms for multifidelity information fusion that use such an approach towards improving the representation of the high-fidelity function with only a few training data points.
