On Bayesian mechanics: a physics of and by beliefs

Interface Focus, Journal Year: 2023, Volume and Issue: 13(3)

Published: April 14, 2023

The aim of this paper is to introduce a field study that has emerged over the last decade, called Bayesian mechanics. mechanics probabilistic mechanics, comprising tools enable us model systems endowed with particular partition (i.e. into particles), where internal states (or trajectories states) system encode parameters beliefs about external their trajectories). These allow write down mechanical theories for look as if they are estimating posterior probability distributions causes sensory states. This provides formal language modelling constraints, forces, potentials and other quantities determining dynamics such systems, especially entail on space statistical manifold). Here, we will review state art in literature free energy principle, distinguishing between three ways which been applied path-tracking, mode-tracking mode-matching). We go examine duality principle constrained maximum entropy both lie at heart discuss its implications.

The Emperor's New Markov Blankets

Behavioral and Brain Sciences, Journal Year: 2021, Volume and Issue: 45

Published: Oct. 22, 2021

The free energy principle, an influential framework in computational neuroscience and theoretical neurobiology, starts from the assumption that living systems ensure adaptive exchanges with their environment by minimizing objective function of variational energy. Following this premise, it claims to deliver a promising integration life sciences. In recent work, Markov blankets, one central constructs have been applied resolve debates philosophy (such as demarcating boundaries mind). aim paper is twofold. First, we trace development blankets starting standard application Bayesian networks, via inference, use literature on active inference. We then identify persistent confusion between formal epistemic tool for novel metaphysical demarcate physical boundary agent its environment. Consequently, propose distinguish "Pearl blankets" refer original "Friston new construct. Second, distinction critically assess resting philosophical problems. suggest would do well differentiating two different research programmes: "inference model" within model."

Osteopathic Care as (En)active Inference: A Theoretical Framework for Developing an Integrative Hypothesis in Osteopathy

Frontiers in Psychology, Journal Year: 2022, Volume and Issue: 13

Published: Feb. 18, 2022

Osteopathy is a person-centred healthcare discipline that emphasizes the body’s structure-function interrelationship—and its self-regulatory mechanisms—to inform whole-person approach to health and wellbeing. This paper aims provide theoretical framework for developing an integrative hypothesis in osteopathy, which based on enactivist active inference accounts. We propose osteopathic care can be reconceptualised under (En)active as unifying framework. Active suggests action-perception cycles operate minimize uncertainty optimize individual’s internal model of lived world and, crucially, consequences their behaviour. argue offers evince mechanisms underlying dyadic triadic (e.g., paediatric care) exchanges outcomes. this underpin across lifespan, from preterm infants elderly those with persistent pain other physical symptoms.

Markov blankets in the brain

Neuroscience & Biobehavioral Reviews, Journal Year: 2021, Volume and Issue: 125, P. 88 - 97

Published: Feb. 17, 2021

Recent characterisations of self-organising systems depend upon the presence a 'Markov blanket': statistical boundary that mediates interactions between inside and outside system. We leverage this idea to provide an analysis partitions in neuronal systems. This is applicable brain architectures at multiple scales, enabling into single neurons, regions, brain-wide networks. treatment based canonical micro-circuitry used empirical studies effective connectivity, so as speak directly practical applications.

On the Importance of Being Flexible: Dynamic Brain Networks and Their Potential Functional Significances

Frontiers in Systems Neuroscience, Journal Year: 2022, Volume and Issue: 15

In this theoretical review, we begin by discussing brains and minds from a dynamical systems perspective, then go on to describe methods for characterizing the flexibility of dynamic networks. We discuss how varying degrees kinds may be adaptive (or maladaptive) in different contexts, specifically focusing measures related either more disjoint or cohesive dynamics. While disjointed useful assessing neural entropy, potentially serve as proxy self-organized criticality fundamental property enabling behavior complex systems.
