在随机动力系统的这种处理中,我们考虑在非平衡稳态条件独立的存在性和识别。这些独立性保证了一个特定的状态划分,其中内部状态在统计上被毯子状态与外部状态隔离。这种分区的存在对内部状态的信息几何有着有趣的影响。简而言之,这种几何学可以被解读为感知的物理学,其中内部状态看起来好像是推断外部状态。然而,这种分区的存在以及潜在密度的函数形式还有待确定。在这里,使用洛伦兹系统作为随机混沌的基础上,我们利用亥姆霍兹分解和多项式展开参数化的稳态密度的自信息或自信息。然后,我们将展示如何马尔可夫毯可以识别使用伴随的海森-来描述内部和外部状态之间的耦合在一个广义的同步或同步的混乱。我们的结论是,这种同步性可能为生物学中(自主或主动)感知的基本形式提供了数学基础。
In this treatment of random dynamical systems, we consider the existence—and identification—of conditional independencies at nonequilibrium steady-state. These independencies underwrite a particular partition of states, in which internal states are statistically secluded from external states by blanket states. The existence of such partitions has interesting implications for the information geometry of internal states. In brief, this geometry can be read as a physics of sentience, where internal states look as if they are inferring external states. However, the existence of such partitions—and the functional form of the underlying densities—have yet to be established. Here, using the Lorenz system as the basis of stochastic chaos, we leverage the Helmholtz decomposition—and polynomial expansions—to parameterise the steady-state density in terms of surprisal or self-information. We then show how Markov blankets can be identified—using the accompanying Hessian—to characterise the coupling between internal and external states in terms of a generalised synchrony or synchronisation of chaos. We conclude by suggesting that this kind of synchronisation may provide a mathematical basis for an elemental form of (autonomous or active) sentience in biology.
