Data-Driven Model Selections of Second-Order Particle Dynamics via Integrating Gaussian Processes with Low-Dimensional Interacting Structures

no code implementations1 Nov 2023 Jinchao Feng, Charles Kulick, Sui Tang

In this paper, we focus on the data-driven discovery of a general second-order particle-based model that contains many state-of-the-art models for modeling the aggregation and collective behavior of interacting agents of similar size and body type.

We present a comprehensive examination of learning methodologies employed for the structural identification of dynamical systems.

Learning Interaction Variables and Kernels from Observations of Agent-Based Systems

no code implementations4 Aug 2022 Jinchao Feng, Mauro Maggioni, Patrick Martin, Ming Zhong

Dynamical systems across many disciplines are modeled as interacting particles or agents, with interaction rules that depend on a very small number of variables (e. g. pairwise distances, pairwise differences of phases, etc...), functions of the state of pairs of agents.

Model Uncertainty and Correctability for Directed Graphical Models

no code implementations17 Jul 2021 Panagiota Birmpa, Jinchao Feng, Markos A. Katsoulakis, Luc Rey-Bellet

Probabilistic graphical models are a fundamental tool in probabilistic modeling, machine learning and artificial intelligence.

Learning particle swarming models from data with Gaussian processes

no code implementations4 Jun 2021 Jinchao Feng, Charles Kulick, Yunxiang Ren, Sui Tang

As a byproduct, we show we can obtain a parametric learning rate in $M$ for the posterior marginal variance using $L^{\infty}$ norm, and the rate could also involve $N$ and $L$ (the number of observation time instances for each trajectory), depending on the condition number of the inverse problem.
