This paper deals with the problem of jointly identifying graph filters and separating their (sparse) input signals from a mixture of diffused graph signals.
Blind identification of invertible graph filters with multiple sparse inputs. C Ye, R Shafipour, G Mateos. 2018 26th European Signal Processing Conference ...
Dec 23, 2024 · We study a blind deconvolution problem on graphs, which arises in the context of localizing a few sources that diffuse over networks.
