An approach to implementing variational Bayesian inference in biological systems is considered, under which the thermodynamic free energy of a system directly encodes its variational free energy. In the case of the brain, this assumption places constraints on the neuronal encoding of generative and recognition densities, in particular requiring a stochastic population code. The resulting relationship between thermodynamic and variational free energies is prefigured in mind–brain identity theses in philosophy and in the Gestalt hypothesis of psychophysical isomorphism.

心理物理身份和自由能


考虑了一种在生物系统中实现变分贝叶斯推理的方法，在该方法下系统的热力学自由能直接编码其变分自由能。就大脑而言，这种假设对生成和识别密度的神经元编码施加了限制，特别是需要随机群体代码。由此产生的热力学和变分自由能之间的关系在哲学中的心脑同一性论文和心理物理学同构的格式塔假说中得到了预示。
