PLoS One
. 2024 Oct;
19(10):e0306704.
PMID: 39418246
The recent COVID-19 pandemic has thrown the importance of accurately forecasting contagion dynamics and learning infection parameters into sharp focus. At the same time, effective policy-making requires knowledge of the...

. 2024 Aug;
110(1-1):014121.
PMID: 39160966
Deriving closed-form analytical expressions for reduced-order models, and judiciously choosing the closures leading to them, has long been the strategy of choice for studying phase- and noise-induced transitions for agent-based...

PNAS Nexus
. 2024 Apr;
3(4):pgae063.
PMID: 38560526
Network structures underlie the dynamics of many complex phenomena, from gene regulation and foodwebs to power grids and social media. Yet, as they often cannot be observed directly, their connectivities...

Friston K, Da Costa L, Sakthivadivel D, Heins C, Pavliotis G, Ramstead M, et al.
Phys Life Rev
. 2023 Sep;
47:35-62.
PMID: 37703703
This paper describes a path integral formulation of the free energy principle. The ensuing account expresses the paths or trajectories that a particle takes as it evolves over time. The...

Proc Natl Acad Sci U S A
. 2023 Feb;
120(7):e2216415120.
PMID: 36763529
Computational models have become a powerful tool in the quantitative sciences to understand the behavior of complex systems that evolve in time. However, they often contain a potentially large number...

Stat Comput
. 2022 May;
32(2):34.
PMID: 35527984
We propose a novel method for drift estimation of multiscale diffusion processes when a sequence of discrete observations is given. For the Langevin dynamics in a two-scale potential, our approach...

Proc Math Phys Eng Sci
. 2022 Feb;
477(2256):20210518.
PMID: 35153603
This paper develops a Bayesian mechanics for adaptive systems. Firstly, we model the interface between a system and its environment with a Markov blanket. This affords conditions under which states...

Chaos
. 2021 Jul;
31(6):061103.
PMID: 34241317
In this paper, we study phase transitions for weakly interacting multiagent systems. By investigating the linear response of a system composed of a finite number of agents, we are able...

Proc Math Phys Eng Sci
. 2021 Jan;
476(2244):20200688.
PMID: 33402877
We study the response to perturbations in the thermodynamic limit of a network of coupled identical agents undergoing a stochastic evolution which, in general, describes non-equilibrium conditions. All systems are...

PMID: 30999473
We analyze a variant of the Desai-Zwanzig model [J. Stat. Phys. 19, 1 (1978)JSTPBS0022-471510.1007/BF01020331]. In particular, we study stationary states of the mean field limit for a system of weakly...
