Distributed Cartesian Power Graph Segmentation for Graphon Estimation

2018 · arXiv (Cornell University)

We study an extention of total variation denoising over images to over Cartesian power graphs and its applications to estimating non-parametric network models. The power graph fused lasso (PGFL) segments a matrix by exploiting a …
