Customers include banks and energy councils. 2018-02-24 · In physics and probability theory, mean field theory (MFT also known as self-consistent field theory) studies the behavior of large and complex stochastic models by studying a simpler model. Mean-Field Theory. Mean field theories (MFTs) are, in general, derived from variational principles and have been shown to suffer from serious drawbacks, particularly close to second order phase transitions, which are characterized by the fact that long-range order (LRO) parameter is a continuous function of temperature, vanishing at the critical temperature, Tc. Recall that the fixed points of the naive mean field algorithm are optimizers of the mean-field approximation to the Gibbs variational problem. This approach is "mean" in that it is the average/expectation/LLN version of the Gibbs sampler, hence ignoring second-order (stochastic) effects (see, e.g., M. Wainwright and M. Jordan, (2.14) and (2.15)).

Use of the term "mean field" is inspired by mean-field theory in physics, which considers the behaviour of systems of large numbers of particles where individual particles have negligible impact upon the system. 2021-03-30 · The self-consistent mean-field approximation is derived using the effective nucleon–nucleon Skyrme-type interaction.

VB methods allow us to re-write statistical inference problems (i.e. infer the value of a random variable given the value of another random variable) as term mean eld comes for an analogy with the mean eld models in mathematical physics, which analyse the behavior of many identical particles (see for instance Sznitman’s notes [122]).
