Entropy, 2021 In theoretical biology, we are often interested in random dynamical systems—like the brain—that appear to model their environments. This can be formalized by appealing to the existence of a (possibly non-equilibrium) steady state, whose density preserves

Stochastic Chaos and Markov Blankets [PDF]
Entropy, 2021 In this treatment of random dynamical systems, we consider the existence—and identification—of conditional independencies at nonequilibrium steady-state.

Fast Markov blanket discovery [PDF]
, 2020 In this thesis, we address the problem of learning the Markov blanket of a quantity from data in an efficient manner. The discovery of the Markov blanket is useful in the feature subset selection problem and in discovering the structure of a Bayesian network.

Causal surgery under a Markov blanket
Behavioral and Brain Sciences, 2022 Bruineberg et al provide compelling clarity on the roles Markov blankets could (and perhaps should) play in the study of life and mind. However, here we draw attention to a further role blankets might play: as a hypothesis about cognition itself. People and other animals may use blanket-like representations to model the boundary between themselves ...

Classification using Markov blanket for feature selection
2009 IEEE International Conference on Granular Computing, 2009 Selecting relevant features is in demand when a large data set is of interest in a classification task. It produces a tractable number of features that are sufficient and possibly improve the classification performance. This paper studies a statistical method of Markov blanket induction algorithm for filtering features and then applies a classifier ...

Minimization of prediction errors during cerebral embryogenesis and the emergence of agency [PDF]
Frontiers in Systems NeuroscienceA theory of self-organization in the central nervous system is described, proposing that additive and dissipative synaptodendritic summation leads to synchronous oscillation as the equilibrium state, thereby underpinning a primary mechanism of prediction

Multi-Source Causal Invariance for Cuffless Blood Pressure Estimation Based on Photoplethysmography Signal Features [PDF]
SensorsCuffless continuous blood pressure (BP) monitoring is essential for personal health management. However, its accuracy is challenged by the diversity and heterogeneity of physiological data sources.

Thoughtseeds: A Hierarchical and Agentic Framework for Investigating Thought Dynamics in Meditative States [PDF]
EntropyThe Thoughtseeds Framework introduces a novel computational approach to modeling thought dynamics in meditative states, conceptualizing thoughtseeds as dynamic attentional agents that integrate information.

Markov Blanket Density and Free Energy Minimization
CoRRThis paper presents a continuous, information-theoretic extension of the Free Energy Principle through the concept of Markov blanket density, i.e., a scalar field that quantifies the degree of conditional independence between internal and external states at each point in space (ranging from 0 for full coupling to 1 for full separation). It demonstrates
