Pole-Zero Geometry, Model Reduction, and Identifiability in Sensory Adaptation
Gunn Kim
Sensory adaptation provides a concrete setting in which low-order system identification can fail qualitatively. We show that one fixed higher-order adaptive system composed entirel…
Dynamical phase selection controls compute scaling in looped transformers
Gunn Kim
A looped transformer performs inference by iterating a weight-tied map, making its computation a dynamical process whose cost is set by the resulting inference dynamics. Here we sh…
Path-Measure Dynamics of Attention-Driven World Models: A Nonlocal Onsager--Machlup Approach
Gunn Kim
Attention enables a world model to condition on its entire history, providing long-term memory that facilitates long-range predictions. While the local Onsager--Machlup theory in o…
A Path-Space Formulation of Prediction in World Models: From a Single Action to Prediction, Planning, and Irreversibility
Gunn Kim
We propose a path-space formulation of prediction in AI world models. Rather than sequences of one-step conditional distributions, we argue that a world model implicitly defines a…
Non-Equilibrium Stochastic Dynamics as a Unified Framework for Insight and Repetitive Learning: A Kramers Escape Approach to Continual Learning
Gunn Kim
Continual learning in artificial neural networks is fundamentally limited by the stability--plasticity dilemma: systems that retain prior knowledge tend to resist acquiring new kno…
Critical Scaling and Metabolic Regulation in a Ginzburg--Landau Theory of Cognitive Dynamics
Gunn Kim
We formulate a phenomenological effective field theory in which biological intelligence emerges as a macroscopic order parameter sustained by continuous metabolic flux. By modeling…
Topological Reorganization and Coordination-Controlled Crossover in Synchronization Onset on Regular Lattices
Gunn Kim
The transition to global synchronization in coupled dynamical systems is governed by the interplay between coupling strength and structural topology. Although abrupt, first-order-l…
Thermodynamic Optimization of Sensory Adaptation via Game-Theoretic Path Integrals
Gunn Kim
Biological sensory systems, from \textit{E.~coli} chemotaxis to sensory neurons in \textit{C.~elegans}, achieve reliable adaptation over wide dynamic ranges despite operating in st…
Entropy-Generated Attention Beyond Softmax and Entmax: Kaniadakis and Reciprocal-Symmetric Abe Operators
Gunn Kim
We derive two attention operators from generalized statistical entropies. Kaniadakis entropy yields an exact full-support normalization whose weights and low-score sensitivities de…
Impact of the topology of global macroeconomic network on the spreading of economic crises
Kyu-Min Lee, Jae-Suk Yang, Gunn Kim +3
Throughout economic history, the global economy has experienced recurring crises. The persistent recurrence of such economic crises calls for an understanding of their generic feat…
