framework

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.

claim

method

Gradient Descent on Free Energy
implements
Optimization procedure for simultaneously updating action selection and perception; uses step size ζ (default 4).
Softmax Function
implements
Neuronal dynamics computed from free energy gradients; interpreted as average firing rate of neural populations.

Perception-Action Cycleconcept0.838
Circular causality between perception and action; central to enactive interpretation
Perception Stageconcept0.835
First stage of DiffLogic CA update where each cell gathers information from neighboring cells via logic gate kernels
field-like perceptionconcept0.807
Perception that is smooth and can be evaluated at any point, like a differentiable field; Antra's functionalist interpretation.
Second-Order Perceptionconcept0.799
CIMC's proposed computational structure of consciousness: perception that perception is occurring, non-inferential and synchronous with its content
Perceptual Fieldconcept0.797
Area in space and time an agent can survey to find alternative paths to a goal; increases with collective size.
Feelingconcept0.796
The experiential measure of life; a living process is congruent with and governed by feeling, and the feeling a place presents is the measure of its life.
Perception is a form of action; perception and action cannot be pulled apartclaim0.793
Enactive consequence: active sampling of world means perception inherently involves action
Perceptual Learningconcept0.791
Process of inferring causes of sensory information; unified with value learning as integral aspects of free energy minimization.
