New method infers particle dynamics and population heterogeneity

By PulseAugur Editorial · [1 sources] · 2026-06-02 04:00

Researchers have developed a new maximum likelihood approach to infer complex dynamical models and population heterogeneity from particle trajectory data. This method is particularly effective for short trajectories and provides a measure of uncertainty for heterogeneity estimates. The technique is designed to systematically infer models for actively driven entities by analyzing temporal fluctuations and inter-particle variability. AI

A Likelihood Approach for Inference of Population Heterogeneity in Particle Ensembles with Second-Order Langevin Dynamics

arXiv:2411.08692v2 Announce Type: replace-cross Abstract: The inherent complexity of biological agents often leads to motility behavior that appears to have random components. Robust stochastic inference methods are therefore required to understand and predict the motion patterns…
