Simultaneous Low-rank Component and Graph Estimation for High-dimensional Graph Signals: Application to Brain Imaging

no code implementations • 26 Sep 2016 • Rui Liu, Hossein Nejati, Seyed Hamid Safavi, Ngai-Man Cheung

We propose an algorithm to uncover the intrinsic low-rank component of a high-dimensional, graph-smooth and grossly-corrupted dataset, under the situations that the underlying graph is unknown.
