DEM II: Dynamic Entropy Model II; Entropy Collapse and Emergent Probabilities in Recursive Systems

The article introduces the Dynamic Entropy Model II (DEM II), a post-Shannonian framework that models entropy as an emergent, recursive, and observer-sensitive flow within open systems.
DEM II addresses the limitations of classical Shannon entropy by considering observation collapse, emergent probability distributions, and chaotic environmental coupling.
Entropy in real-world systems is portrayed as an evolving property influenced by interactions, collapse events, and environmental entanglement, rather than a passive function of known probabilities.
It integrates tools from information theory, control theory, stochastic dynamics, AI, and philosophy of physics to redefine entropy as an actively regulated, emergent structure.
Core contributions of DEM II include a dynamic entropy model accounting for observer interaction, observation-induced probability reweighting, and an entropy-feedback control mechanism.
The article discusses simulation goals comparing classical Shannon entropy with DEM II entropy under various scenarios like biased vs unbiased starting distributions and feedback entropy controllers.
Applications of DEM II range from quantum systems to AI ethics, ecological modeling, cognitive architectures, and generative AI, showcasing its diverse potential domains.
The paper delves into technical aspects like time-dependent entropy evolution equations, probabilistic evolution models, entropy feedback control mechanisms, and entropy engineering from an optimal control perspective.
The proposed theory envisions entropy as a steerable dimension, essential for fields like AI, quantum computing, ecosystem modeling, and neuromorphic hardware.
The article emphasizes the synergistic architecture of DEM and DREM for modeling learning systems and adaptive autonomy, paving the way for Artificial General Intelligence (AGI) and intelligent self-regulation.
By bridging information theory, control theory, thermodynamics, machine learning, and biological adaptation, DEM II offers a fresh perspective on the interplay between entropy and complex systems.
