This study redefines cognition as choice that reduces uncertainty, proposing information as free energy. This framework enables new analysis of complex cognitive systems and their failure modes.
Area of Science:
- Cognitive Science
- Information Theory
- Statistical Physics
Background:
- Cognition fundamentally involves reducing uncertainty, implying an external information source.
- Traditional information theory (Shannon entropy) is insufficient for path-dependent, non-ergodic systems where time and ensemble averages diverge.
Purpose of the Study:
- To extend information theory to non-ergodic systems by conceptualizing information as free energy.
- To develop new analytical tools for understanding complex cognitive dynamics and failure modes.
Main Methods:
- Utilizing directed homotopy groupoids instead of traditional groups for algebraic expression of complex dynamic topologies.
- Extending the Data Rate Theorem by linking control and information theories through spontaneous symmetry breaking analogies.
- Constructing dynamic empirical Onsager models based on the Legendre transform of path-dependent information uncertainties.
Main Results:
- Information is identified as a form of free energy, applicable to non-ergodic cognitive systems.
- A novel mathematical framework using directed homotopy groupoids is established for complex system dynamics.
- The methodology allows for the construction of dynamic Onsager models from information uncertainties.
Conclusions:
- The proposed framework offers new analytic tools for studying cognitive phenomena across various scales.
- Understanding information as free energy provides insights into failure modes in physiological, systemic, and economic contexts.
