Learning heat diffusion graphs

NettetFig. 1: Decomposition of a graph signal (a) in four localized simple components (b), (c), (d), (e). Each component is a heat diffusion process (e−τ L) at time τ that has started from different network nodes ( δn ). The size and the color of each ball indicate the value of the signal at each vertex of the graph. NettetTwo-dimensional transient heat conduction in multi-layered composite media with temperature dependent thermal diffusivity using floating random walk Monte-Carlo method.
