Information Theory: Information Theory for Fields (Ann. Phys. 3/2019)
Torsten A. Enßlin · Annalen der Physik · 2019
Feynman graph representation of an algorithm based on information field theory to estimate the level of non-Gaussianity in the Cosmic Microwave Background, which is shown in the background. As described by Enßlin in article number andp.201800127, each of the diagrams expresses a term that depends on the data in a non-linear way and has to be evaluated numerically. The terms are combined by addition and division.
