[HTML][HTML] Federated inference and belief sharing

KJ Friston, T Parr, C Heins, A Constant… - Neuroscience & …, 2024 - Elsevier
This paper concerns the distributed intelligence or federated inference that emerges under
belief-sharing among agents who share a common world—and world model. Imagine, for …

Between order and chaos

JP Crutchfield - Nature Physics, 2012 - nature.com
What is a pattern? How do we come to recognize patterns never seen before? Quantifying
the notion of pattern and formalizing the process of pattern discovery go right to the heart of …

The anatomy of choice: active inference and agency

K Friston, P Schwartenbeck, T FitzGerald… - Frontiers in human …, 2013 - frontiersin.org
This paper considers agency in the setting of embodied or active inference. In brief, we
associate a sense of agency with prior beliefs about action and ask what sorts of beliefs …

Thermodynamics of modularity: Structural costs beyond the Landauer bound

AB Boyd, D Mandal, JP Crutchfield - Physical Review X, 2018 - APS
Information processing typically occurs via the composition of modular units, such as the
universal logic gates found in discrete computation circuits. The benefit of modular …

Occam's quantum strop: Synchronizing and compressing classical cryptic processes via a quantum channel

JR Mahoney, C Aghamohammadi, JP Crutchfield - Scientific reports, 2016 - nature.com
A stochastic process' statistical complexity stands out as a fundamental property: the
minimum information required to synchronize one process generator to another. How much …

Causal asymmetry in a quantum world

J Thompson, AJP Garner, JR Mahoney, JP Crutchfield… - Physical Review X, 2018 - APS
Causal asymmetry is one of the great surprises in predictive modeling: The memory required
to predict the future differs from the memory required to retrodict the past. There is a …

Informational and causal architecture of discrete-time renewal processes

SE Marzen, JP Crutchfield - Entropy, 2015 - mdpi.com
Renewal processes are broadly used to model stochastic behavior consisting of isolated
events separated by periods of quiescence, whose durations are specified by a given …

General anesthesia reduces complexity and temporal asymmetry of the informational structures derived from neural recordings in Drosophila

RN Muñoz, A Leung, A Zecevik, FA Pollock… - Physical Review …, 2020 - APS
We apply techniques from the field of computational mechanics to evaluate the statistical
complexity of neural recording data from fruit flies. First, we connect statistical complexity to …

Predictive rate-distortion for infinite-order Markov processes

SE Marzen, JP Crutchfield - Journal of Statistical Physics, 2016 - Springer
Predictive rate-distortion analysis suffers from the curse of dimensionality: clustering
arbitrarily long pasts to retain information about arbitrarily long futures requires resources …

Transient dissipation and structural costs of physical information transduction

AB Boyd, D Mandal, PM Riechers, JP Crutchfield - Physical review letters, 2017 - APS
A central result that arose in applying information theory to the stochastic thermodynamics of
nonlinear dynamical systems is the information-processing second law (IPSL): the physical …
