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.

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.
