FIG. 3.

Function classes (3 × 3) on the landscape. Each spot in both panels represents a function class, or family. (a) The information landscape shows the orientation of the plane with respect to the 3D landscape. (b) A set of 12 panels, one each for the complete set of possible values of the multi-information, Ω, for the 3 × 3 functions. The plane is the projected diagonal plane of the 3D landscape, the gray spots are the same for each panel and show the positions of all of the families of functions. The red spots are the families specific for each specific value of Ω. The upper left panel has no function as the information content of the uniform functions is zero, and all Δ's are zero. 3D, three-dimensional.
