Webwhile remaining tractable. To achieve this we run a Poisson point process over the square [0,1]2, with an intensity proportional to a kernel W(x,y) and identify every couple of vertices of the graph with a subset of the square, adding an edge between them if there is a point in such subset. This ensures unconditional independence among edges ... WebPoisson kernel is the main result of this section.
