Markov Blanket

A statistical partition of states that separates internal states from external hidden states; fundamental to self-organization in the paper.

thinker

Judea Pearl
introduces
Developed causal graph models and the do-operator, foundational to modern causal inference.

framework

Active Inference
associated_withimplements
Foundational framework by Karl Friston; the paper extends it to three hierarchical levels for modeling meta-awareness.
Free Energy Principle
associated_with
A foundational variational principle from statistical physics that formalizes how self-organizing systems maintain structural integrity and adapt to their environment by minimizing free energy—a mathematical bound on surprise or prediction error. Originally developed by Karl Friston, the framework unifies action, perception, and learning as processes of active inference, where systems both update internal models of the world and act upon it to reduce the divergence between predictions and observations.
Quantum Free Energy Principle (qFEP)
extends
Reformulation of FEP in quantum information theory terms; the primary formal apparatus of the paper

method

Spectral Graph Theory
implements
Technique using principal eigenvectors to identify densest clusters; applied to find principal Markov blanket in simulations.

concept

Generative Model
associated_with
Agent's internal probabilistic model of environment; enables belief inference about hidden states given outcomes.
Circular causality
associated_with
The reciprocal causal coupling between internal/external states via sensory/active states.
