Mean field approximation[2], which is originated in statistical physics, has been frequently used in practical situations in order to circumvent this difficulty. In the context of statistical physics several advanced theories have been known, such as the TAP approach[3], linear

AU - Tembine, Hamidou. N1 - Funding Information: This research work is supported by U.S. Air Force Office of Scientific Research under grant number FA9550-17-1-0259. The author is grateful to Prof. Boualem Djehiche for useful comments on the Wiener Chaos Expansions in mean-field-type games. This enables us to broaden the scope of mean field game theory and infer MFG models of large real-world systems via deep inverse reinforcement learning. Our method learns both the reward function and forward dynamics of an MFG from real data, and we report the first empirical test of a mean field game model of a real-world social media population.

Now that we have a theoretical understanding of how this all works, let's see it in action. Perhaps the simplest case (and I'm using the word "simple" in relative terms here) is the univariate Gaussian with a Gaussian prior on its mean and a inverse Gamma prior on its variance (from Example 1). Applications of mean-field games go way beyond the realm of animal swarms! Recently, Lasry and Lions exploited mean-field game theory to design new decision making processes for financial, technological and industrial innovation, as they launched the company mfg labs in Paris!
