    indeed, it is not easy to understand this approach, which seem to derive from the concept of thermodynamics :

    Thank for the article

    In classical physics, dynamical equations can be derived from a principle of least action.

    We can ask the inverse question, which dynamical equations mininimize an action? This question has been addressed by Tonti (and others).

    Here is some related work on energy functions for "self-organizing maps".

    Perhaps closer to the technicalities of the article, many forms of approximate inference can be stated using variational language.
