Source Localization on Graphs via l1 Recovery and Spectral Graph Theory

24 Mar 2016Rodrigo PenaXavier BressonPierre Vandergheynst

We cast the problem of source localization on graphs as the simultaneous problem of sparse recovery and diffusion kernel learning. An l1 regularization term enforces the sparsity constraint while we recover the sources of diffusion from a single snapshot of the diffusion process... (read more)
