Free energy and inference in living systems

Chang Sub Kim

Organisms are nonequilibrium, stationary systems self-organized via spontaneous symmetry breaking and undergoing metabolic cycles with broken detailed balance in the environment. T…

Bayesian mechanics of perceptual inference and motor control in the brain

Chang Sub Kim

The free energy principle (FEP) in the neurosciences stipulates that all viable agents induce and minimize informational free energy in the brain to fit their environmental niche.…

Classical and quantum dissipative dynamics in Josephson junctions: an Arnold problem, bifurcation and capture into resonance

Dmitrii Pashin, Arkady M. Satanin, Chang Sub Kim

We theoretically study the phase dynamics in Josephson junctions, which maps onto the oscillatory motion of a point-like particle in the washboard potential. Under appropriate driv…

Recognition Dynamics in the Brain under the Free Energy Principle

Chang Sub Kim

We formulate the computational processes of perception in the framework of the principle of least action by postulating the theoretical action as a time integral of the free energy…

The free energy principle for action and perception: A mathematical review

Christopher L. Buckley, Chang Sub Kim, Simon McGregor +1

The 'free energy principle' (FEP) has been suggested to provide a unified theory of the brain, integrating data and theory relating to action, perception, and learning. The theory…

Statistical work-energy theorems in deterministic dynamics

Chang Sub Kim

We theoretically explore the Bochkov-Kuzovlev-Jarzynski-Crooks work theorems in a finite system subject to external control, which is coupled to a heat reservoir. We first elaborat…
