Vertex Centrality Reconstruction in an Inverse Problem for Information Diffusion
Yixian Gao, Songshuo Li, Yang Yang
We consider an inverse problem in information diffusion modeled by random walks on combinatorial graphs. The problem concerns reconstruction of vertex centrality from the distribut…

Vertex Weight Reconstruction in the Gel'fand's Inverse Problem on Connected Weighted Graphs
Songshuo Li, Yixian Gao, Ru Geng +1
We consider the reconstruction of the vertex weight in the discrete Gel'fand's inverse boundary spectral problem for the graph Laplacian. Given the boundary vertex weight and the e…
