Active inference models do not contradict folk psychology

Published: March 9, 2022

Abstract Active inference offers a unified theory of perception, learning, and decision-making at computational neural levels description. In this article, we address the worry that active may be in tension with belief–desire–intention (BDI) model within folk psychology because it does not include terms for desires (or other conative constructs) mathematical level To resolve concern, first provide brief review historical progression from predictive coding to inference, enabling us distinguish between formulations motor control (which need have under psychology) decision processes do psychology). We then show that, despite superficial when viewed description, formalism contains are readily identifiable as encoding both objects desire strength psychological demonstrate simple simulations an agent motivated leave dark room different reasons. Despite their consistency, further how increase granularity folk-psychological descriptions by highlighting distinctions drives seek information versus reward—and also offer more precise, quantitative predictions. Finally, consider implicitly components partial analogues (i.e., “as if” desires) systems describable broader free energy principle which conforms.

The Problem of Meaning: The Free Energy Principle and Artificial Agency

Frontiers in Neurorobotics, Journal Year: 2022, Volume and Issue: 16

Published: June 23, 2022

Biological agents can act in ways that express a sensitivity to context-dependent relevance. So far it has proven difficult engineer this capacity for relevance artificial agents. We give problem the label "problem of meaning". The meaning could be circumvented if intelligence researchers were design based on assumption continuity life and mind. In paper, we focus proposal made by enactive cognitive scientists possess sensorimotor autonomy-stable, self-sustaining patterns interaction ground values, norms goals necessary encountering meaningful environment. More specifically, consider whether Free Energy Principle (FEP) provide formal tools modeling autonomy. There is currently no consensus how understand relationship between science FEP. However, number recent papers have argued two frameworks are fundamentally incompatible. Some argue biological systems exhibit historical path-dependent learning absent from minimize free energy. Others energy minimizing system would fail satisfy key condition agency referred as "interactional asymmetry". These critics question claim defend paper FEP used formally model autonomy adaptivity. will too soon conclude undeniable conceptual differences but our view each something important offer. needs solution provides meaning. Enactive properties argues constitutive agency. Our conclusion active inference models way which think about address problems engineering adaptivity terms. end engaging more closely with formalism its further developments benefit those working within framework.

Neural and phenotypic representation under the free-energy principle

Neuroscience & Biobehavioral Reviews, Journal Year: 2020, Volume and Issue: 120, P. 109 - 122

Published: Nov. 30, 2020

The aim of this paper is to leverage the free-energy principle and its corollary process theory, active inference, develop a generic, generalizable model representational capacities living creatures; that is, theory phenotypic representation. Given their ubiquity, we are concerned with distributed forms representation (e.g., population codes), whereby patterns ensemble activity in tissue come represent causes sensory input or data. inference framework rests on Markov blanket formalism, which allows us partition systems interest, such as biological systems, into internal states, external (active sensory) states render conditionally independent each other. In framework, capacity creatures emerges consequence Markovian structure nonequilibrium dynamics, together entail dual-aspect information geometry. This entails modest capacity: have an intrinsic geometry describes trajectory over time state space, well extrinsic encode (the parameters of) probabilistic beliefs about (fictive) states. Building this, describe here how, automatic emergent manner, stimuli can be encoded by groups neurons bound blanket; what known neuronal packet hypothesis. As concrete demonstration type representation, present numerical simulations showing self-organizing ensembles agents sharing right kind generative able recoverable stimulus array.

Examining the Continuity between Life and Mind: Is There a Continuity between Autopoietic Intentionality and Representationality?

Philosophies, Journal Year: 2021, Volume and Issue: 6(1), P. 18 - 18

Published: Feb. 21, 2021

A weak version of the life-mind continuity thesis entails that every living system also has a basic mind (with non-representational form intentionality). The strong same concepts are sufficient to explain minds states) central understanding non-basic representational states). We argue recent work on free energy principle supports following claims with respect thesis: (i) there is between life and mind; (ii) all systems can be described as if they had states; (iii) ’as-if representationality’ entailed by both forms intentionality in minds. In addition this, we renders realism about computation representation compatible (although does not entail computational realism). particular, show how representationality proper grounded representationality’.

An Enactive–Ecological Model to Guide Patient-Centered Osteopathic Care

Healthcare, Journal Year: 2022, Volume and Issue: 10(6), P. 1092 - 1092

Published: June 12, 2022

Osteopaths commonly face complexity and clinical uncertainty in their daily professional practice as primary contact practitioners. In order to effectively deal with complex presentations, osteopaths need possess well-developed reasoning understand the individual patient's lived experience of pain other symptoms how problem impacts personhood ability engage world. We have recently proposed (En)active inference an integrative framework for osteopathic care. The enactivist active frameworks underpin our hypothesis. Here, we present a clinically based interpretation hypothesis by considering ecological niche which care occurs. Active enables patients practitioners disambiguate each other's mental states. patients' states are unobservable must be inferred on perceptual cues such posture, body language, gaze direction response touch hands-on A robust therapeutic alliance centred cooperative communication shared narratives appropriate effective use enable contextualize experiences. Touch enhance alliance, state alignment, biobehavioural synchrony between patient practitioner. Therefore, osteopath-patient dyad provides alignment opportunities construction. Arguably, this can produce experiences reduce prominence given high-level prediction errors-and consequently, top-down attentional focus bottom-up sensory errors, thus minimizing free energy.

We offer a framework for the design and use of Ambient Smart Environments (ASEs) preventive mental health care support. Drawing from Complex Systems Theory (CST) 'E' Cognitive Science (ECS), we claim that ASEs have potential to act in capacity support good health, i.e. supporting dynamics avoid so-called "struck states" (which are, according CST, thought generally underpin forms psychopathology). Here, frame our discussion with what has recently been termed "mind-technology problem". define characterise ASE systems, present some examples, briefly survey existing theoretical work. After introducing essential CST terminology, paper goes on apply explain developmental adaptation continuously changing (smart) environments. Understanding ASE's navigation terms dynamic geometry between attracting repelling points (or local minima/local maxima), allows us develop neurotechnology can augment clinical interventions by predicting upcoming shifts symptomatic outcomes, when intervention (i.e. destabilisation) should take place. further clear directions development such neurotechnology.
