论文摘要
Biehl等人（2020年）对（Friston，2013年）的自由能原理提出了一些有趣的观察结果。我们使用这些观察结果来讨论承载自由能原理的技术论点。这项讨论的重点是具有马尔可夫毯子的稀疏耦合系统中的各种状态（子集的子集）之间的螺线管耦合，以及随后的贝叶斯力学所暗示的精确和近似贝叶斯推断之间的区别。
Biehl et al (2020) present some interesting observations on an early formulation of the free energy principle in (Friston, 2013). We use these observations to scaffold a discussion of the technical arguments that underwrite the free energy principle. This discussion focuses on solenoidal coupling between various (subsets of) states in sparsely coupled systems that possess a Markov blanket - and the distinction between exact and approximate Bayesian inference, implied by the ensuing Bayesian mechanics.
