(a) Left: density plot of the posterior marginal probability densities $q_u(x)$ that node $u$ has node parameter $x$ for an application of our algorithm to a 600-node stochastic block model with three groups. Colors indicate the probabilities and there are 600 columns, one for each node. Right: density plot of the edge function $\omega (x,y)$. (b) The neural network of the worm C. elegans, drawn in real space, as it falls within the body of the worm. Colors represent the average values of the node parameters $x_u$ inferred for each neuron by our algorithm. (c) Network representation of the interstate highways of the contiguous United States. Again, node colors represent the average node parameters $x_u$.
