We study the interplay between the diffusion of a harmful state in a network of contacts and the possibility of individual agents to undertake costly investment to protect themselves against infection ...

We propose graph-driven approaches to image segmentation by developing diffusion processes defined on arbitrary graphs. We formulate a solution to the image segmentation problem modeled as the result ...

Code for a model described by R. Venkatachalapathy. An adjacency matrix is initialized with random weights, which evolve according to some diffusion process, becoming fixed at 0 or 1 if they go beyond ...
